No presente trabalho foi realizado um estudo de alguns aspectos da reação de obtenção de dimetildiclorosilano a partir da reação entre silícios grau químico (SiGQ) ou de elevada pureza (99,999%) e cloreto de metila catalisada por cobre e promotores em reator de leito fluidizado. Foram estudados os efeitos da temperatura sobre o processo de ativação e sobre a reação com o fim de obter um valor aproximado da energia aparente de ativação para cada uma dessas etapas; o efeito do tamanho médio das partículas de silício e do catalisador sobre os parâmetros de desempenho da reação e o de contaminantes usuais do SiGQ, a saber Ca, Fe e Al, sobre silício de elevada pureza (99,999%). Uma discussão sobre o efeito de compensação característico da reação direta foi realizada sendo proposta uma explicação da origem desse efeito, que aparentemente se deve ao caracter anisotrópico da reação, e uma explicação complementar com relação ao papel dos promotores na reação. Os resultados mostraram que a energia aparente de ativação obtida por meio dos experimentos realizados neste estudo encontram-se em valores próximos ao normalmente encontrado na literatura. Aparentemente existe uma variação da seletividade com a variação do tamanho de partícula tanto do silício quanto do catalisador, que se deve ao grau de cobertura da superfície do silício pelo catalisador. Observou-se ainda que os parâmetros de desempenho se correlacionam melhor com a área geométrica do que com a área específica medida pelo método de adsorsão de N2 (BET). Os elementos Ca, Al e Fe, na forma que foram adicionados, mostraram algum efeito sobre os parâmetros de desempenho da reação, porém verificou-se que o efeito das impurezas é maior se estas estiverem presentes originalmente no silício.<br>Some important aspects of dimethyldichlorosilane direct synthesis from methyl chloride and both chemical grade silicon and high purity silicon (99.999%) catalyzed by copper and promoters in a fluidized bed reactor was studied. The effects of temperature on the activation process and on the reaction were studied to obtain an estimate of the apparent activation energy for each process step. The influence of average particle diameter of silicon and of catalyst and the effect of Ca, Al and Fe additions in the catalyst system were also evaluated. A discussion about the so-called isokinetic compensation behavior which is observed in the direct synthesis is presented. The proposed explanation about the origin of this phenomena is based on the anisotropic character of the reaction. A complementary explanation about the mechanism of promoters action was also proposed. The obtained values of apparent activation energies are within the range reported in the literature. Selectivity and activity showed some variation with both catalyst and silicon particle sizes. This behavior was explained in terms of silicon particle coverage by the catalyst system. The performance parameters show better correlation with the geometric area measured by laser diffraction than with the BET area obtained by N2 adsorption. The promoters Ca, Fe and Al have shown effect over the reaction, however these effects were more proeminent if they are originally present in silicon structure.

The acid and base catalyzed simultaneous twin polymerization (STP) of various 2,2′-disubstituted 4H-1,3,2-benzodioxasiline derivatives 2a–d with 2,2′-spirobi[4H-1,3,2-benzodioxasiline] (1) are presented in this paper. The products are nanostructured ternary organic–inorganic hybrid materials consisting of a cross-linked organic polymer, silica and a disubstituted polysiloxane. It can be demonstrated whether and in which extent the copolymerization of the two inorganic fragments of 1 and 2 takes place among the STP and how the molar ratio of the two components determines the structure formation of the resulting hybrid material. Steric and electronic effects of the substituents at the silicon center of 2 on the molecular structure formation and the morphology of the resulting hybrid material were investigated by means of solid state CP MAS 29Si and 13C NMR spectroscopy as well as high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM). The mechanical properties (hardness and Young's modulus) of the hybrid materials were analyzed by means of nanoindentation measurements<br>Dieser Beitrag ist aufgrund einer (DFG-geförderten) Allianz- bzw.

Les poly(silméthylènesiloxane)s, aussi dénommés silicones hybrides, sont constitués d’un squelette portant un groupement méthylène entre 2 unités SiOSi. La synthèse de ces polymères par polycondensation ne permet pas d’atteindre des masses molaires très élevées, contrairement aux produits issus de la polymérisation par ouverture de cycle. Ce manuscrit décrit la procédure choisie pour aboutir à une synthèse contrôlée de poly(silméthylènesiloxane)s, des précurseurs (monomères, amorceurs) aux polymères. Le monomère cyclique silméthylène a été préparé par cyclisation de le 1,3-dichlorotetraméthylsilméthylène. Ce dernier peut être généré par redistribution de sous-produits de l’industrie de type halogénures d’alkylsilanes. Deux voies de redistribution ont été étudiées, la méthylation par le méthyllithium, et la dismutation des chlorosilanes en présence d’AlCl3 et de tétraméthylsilane. Cette dernière méthode conduit à une nouvelle distribution de chlorosilanes et chlorosilméthylènes jamais obtenue auparavant. La polymérisation par ouverture de cycle en présence d’acide triflique du 1,1,3,3,5,5,7,7-octamethyl-2,6-dioxa-1,3,5,7-tetrasilacyclooctane conduit à des poly(silméthylènesiloxane)s terminés silanol. Suivant la pureté du monomère, différentes masses molaires peuvent être atteintes. La température réactionnelle joue un rôle crucial afin d’éviter toute cyclisation des chaînes. Par comparaison avec des monomères organiques conventionnels (ether, oxiranes, etc...), le mécanisme de polymérisation implique deux espèces en équilibre, un ion silyl-oxonium et un ester silyl-triflate. Une augmentation de la température de réaction déplace cet équilibre vers les espèces ioniques, responsables des réactions de rétroscission. Ainsi la température optimale de réaction a été localisée à 25°C. La polymérisation par ouverture de cycle a été également testée en présence de catalyseur (acide triflique) et d’un amorceur (molécule portant une (des) fonction(s) silanol). Dans les conditions de température données, des polymères de masses molaires et de fonctionnalités contrôlées sont obtenus. Ces expériences ouvrent la porte à de nouvelles voies de polymérisation des cyclosiloxanes, mettant en lumière la compétition entre deux mécanismes de polymérisation, la propagation par bouts de chaînes activés (ACE) et par monomères activés (AM)<br>Polysilmethylenesiloxanes are belonging to the “hybrid” silicone family. The presence of a methylene group into the polymer backbone enhances their thermal stability, which is particularly interesting in high-tech applications. The synthesis of such polymers by polycondensation did not so far lead to high molar mass polymers, contrary to those prepared by ring-opening polymerization. The synthesis of such polymers is described in this manuscript, from the monomer to the macromolecule. The silmethylene cyclic dimer, the monomer of interest, is synthesized by cyclization of 1,3-dichlorotetramethylsilmethylene. This latter can be generated from the disproportionation of the direct process residue, a by-product of the silicone industry. The disproportionation proceeds either by methylation with methyl lithium, or by Me/Cl interchange reaction catalyzed by AlCl3 in presence of tetramethylsilane. This latter led to a selective dechlorination of chlorosilanes and chlorosilmethylenes in mild conditions, which has not been yet observed with the DPR. Cationic ring-opening polymerization in presence of triflic acid of such silmethylene cyclic dimer led to bis-silanol polysilmethylenesiloxanes. Depending on the purity of monomer, high molar masses can be targeted. The reaction temperature also plays a critical role in order to avoid any cyclization of the growing chains. While triflic acid plays a role of catalyst, it does not allow controlling molar masses. Comparisons with conventional organic monomers were made to identify the polymerization mechanism which involves two propagating species in equilibrium, a silyl-oxonium ion and a silyltriflate ester. An increase of the reaction temperature shifts this equilibrium towards ionic species, responsible of back- and end-biting reactions. Thus the optimal reaction temperature of ROP of the silmethylene cyclic dimer has been set at 25°C previously and confirmed here. The ROP reaction of the silmethylene cyclic dimer in presence of triflic acid and silanol molecule allows designing the obtained molar masses, while keeping a certain control of end-groups. Variations of molar masses with the silanol content speaks for a polymerization occurring through an activated monomer mechanism. Experiments done to confirm this mechanism open routes to the polymerization of other cyclosiloxanes where the competition between the activated chain end (ACE) and the activated monomer (AM) mechanisms could be controlled

In der vorliegenden Arbeit wurden stickstoffhaltige Monomere ausgehend von aromatischen Aminen oder Lactamen durch Umsetzung mit Chlorsilanen synthetisiert. Die so erhaltenen Derivate wurden mit Hilfe spektroskopischer und thermischer Analysenmethoden umfassend charakterisiert. Auf Basis der stickstoffhaltigen Monomere wurden über unterschiedliche Synthesestrategien organisch-anorganische, nanostrukturierte Hybridmaterialien hergestellt. Durch die thermisch induzierte Zwillingspolymerisation der Monomere 2,2‘-Spirobi[3,4-dihydro-1H-1,3,2-benzodiazasilin] und 1,1’,4,4‘-Tetrahydro-2,2‘-spirobi[benzo[d][1,3,2]-oxazasilin] gelang es, Hybridmaterialien bestehend aus Polyanilin-Formaldehyd-Harzen und Polysilazanen bzw. Siliciumdioxid unter Variation der Reaktionstemperatur herzustellen. Die Untersuchung der entstandenen Materialien erfolgte mittels spektroskopischer Methoden. Die Lactam-Monomere wurden durch die Zugabe von Aminocarbonsäuren zu Polyamid 6/SiO2- bzw. Polysiloxan-Kompositen umgesetzt. Hier stand die Ermittlung der molekularen Struktur, wie auch die Bestimmung des thermischen Verhaltens und der Homogenität der Materialien im Vordergrund. Es konnte gezeigt werden, dass die Synthese der thermoplastischen Kompositmaterialien auch in vergrößertem Maßstab reproduzierbar ist und die Produkte zudem zu Folien extrudierbar sind<br>In the present work nitrogen-containing monomers have been synthesized by reactions of silicon tetrachloride with amines or lactames and were characterized by different spectroscopic and thermal analysis methods. The twin monomers 2,2‘-spirobi[3,4-dihydro-1H-1,3,2-benzodiazasiline] and 1,1’,4,4‘-tetrahydro-2,2‘-spirobi[benzo[d][1,3,2]¬oxazasiline] can be converted to hybrid materials containing polyaniline-formaldehyde resins and polysilazane or SiO2 by thermal induced twin polymerization under variation of the reaction temperature.

The analysis of the molecular structure as well as the investigation of the thermal behavior and the homogeneity of materials was emphasized. It could be shown, that the synthesis can be performed reproducible. Furthermore, it is possible to extrude the thermoplastic composite materials to films

Im Fokus dieser Arbeit stand die Methode Zwillingspolymerisation zur Synthese organisch-anorganischer Hybridmaterialien. Die simultane Zwillingspolymerisation wird als neues Konzept zur gezielten Herstellung homogener, nanostrukturierter Hybridmaterialien unterschiedlicher Zusammensetzung vorgestellt. Hierfür wurden die Zwillingsmonomere 2,2’-Spirobi[4H-1,3,2-benzodioxasilin] und 2,2 Dimethyl-4H-1,3,2-benzodioxasilin in einem Arbeitsschritt gemeinsam polymerisiert. Die erhaltenen Phenolharz-Siliciumdioxid/Dimethylsiloxan-Hybridmaterialien weisen aufgrund einstellbarer Syntheseparameter unterschiedliche Eigenschaftsprofile auf, die systematisch analysiert wurden. Die Charakterisierung der Produkte erfolgte mit Hilfe der Festkörper-NMR-Spektroskopie, Elektronenmikroskopie, DSC, TGA-MS, sowie durch Extraktionsversuche und die Erzeugung und Analyse poröser Materialien. Neben der simultanen Zwillingspolymerisation wird die Synthese, Charakterisierung und thermisch induzierte Polymerisation literaturunbekannter Silicium-Spiroverbindungen mit einfach- oder zweifach substituierter Salicylalkohol-Einheit beschrieben. Hierbei wurden nanostrukturierte Hybridmaterialien mit teils hohem löslichen Anteil erhalten. Die Produktbildung wird in Abhängigkeit von der Entstehung und Weiterreaktion gefundener Chinonmethid-Strukturen diskutiert.

Lors de la polymérisation en suspension du chlorure de vinyle, il se forme sur les parois un dépôt de polychlorure de vinyle (PVC). Ce phénomène, nommé encroûtement, génère des problèmes car il limite la production de PVC et affecte la qualité du produit final. Dans ce contexte, un projet FUI (Fond Unique Interministériel) intitulé «Ecoating», a été financé dans le cadre d’une collaboration entre plusieurs partenaires industriels et universitaires (INEOS ChlorVinyls, Mäder Research, Avenir Group, LPIM, ESPCI-ParisTech). Deux thèses ont vu le jour au LPIM, avec pour but de développer un revêtement (photo)polymère aux propriétés anti-encroûtement durables qui permettrait d’améliorer la qualité du PVC produit, d’augmenter les quantités produites et ainsi d’améliorer la compétitivité des usines de PVC. Cette thèse s’inscrit dans le développement d’un vernis photopolymère répondant au cahier des charges. Pour éviter l’encroûtement des réacteurs, il est nécessaire de stopper une étape du mécanisme d’encroûtement comme l'adsorption sur les parois du réacteur d’un copolymère nommé Acvagen Graft Copolymer (AGC). Ce copolymère est très actif dans le phénomène d’encroûtement (site de nucléation) et se trouve principalement dans la phase aqueuse du milieu réactionnel. La stratégie de recherche élaborée dans ce projet a été basée sur le développement d'un revêtement photopolymère présentant une faible affinité pour l'eau et devant adhérer à la surface des réacteurs pour éviter la formation de croûte. Les polymères à base de fluoroacrylates ont été les premiers candidats choisis dans cette étude du fait que leurs propriétés exceptionnelles (faible énergie de surface, stabilité chimique et haute hydrophobicité...) pouvaient éviter l'adsorption de l'AGC sur les parois du réacteur, et par conséquent le développement de la croûte. Une recherche bibliographique a été réalisée pour comprendre le comportement particulier de ces molécules qui migrent vers la surface du film et s’organisent en surface pour donner des surfaces hydrophobes. Des mélanges de résines fluoroacryliques modèles ont été testés pour évaluer le caractère hydrophobe du revêtement, comprendre la migration des molécules de fluor vers l’interface en fonction de la nature de substrat et aussi déterminer l’influence de l’ajout d’additifs fluorés au mélange sur les propriétés globales du film. Cette étude nous a permis de comprendre l’influence de l’additif fluoré sur les propriétés chimiques et physiques du film. À l’échelle du laboratoire des tests d’immersion de ces revêtements déposés sur l’acier inoxydable ont étés réalisés dans l’eau chaude (80°C) afin de caractériser leur caractère hydrophobe en fonction du vieillissement dans l’eau chaude ainsi que l’adhésion du film au substrat. Nous avons observé une diminution de l'hydrophobicité de la surface du film au cours du temps lors d’une immersion. [...]<br>Our scientific approach has explored different strategies to develop a durable UV-cured coating with antifouling properties to prevent the crust formation. Firstly, the potential of fluoroacrylate photocurable coatings was exhaustively investigated. Indeed, their outstanding properties (low surface energy, chemical stability and high hydrophobicity...) could limit the adsorption of the AGC on the reactor walls and further encrusting. A bibliographic research highlighted the behavior of fluorinated monomers on film surface and the parameters affecting the hydrophobic properties. Different fluorinated monomers were selected. At low concentration, they provide hydrophobic surfaces on 316L stainless steel, the reference substrate. However, a decrease of the films surface hydrophobicity in hot water was observed with time, and was attributed to a disorganization of the fluorinated chains on the coating surface. An optimization of the amount of fluoroacrylate monomer was performed by confocal Raman microscopy (CRM) to promote the fluorinated chains stability on the surface before and after immersion in hot water at 80°C. The beneficial effect was found maximal at a concentration ranging from 1 to 1.8 wt%. However, even after this optimization, a decrease of the film surface hydrophobicity was observed for increased immersion time in hot water. Therefore, optimized fluoroacrylate monomer concentration was combined with alternated thermal/immersion post-treatment and has conducted to more stable photocured films. This result was attributed to a rigidification of the fluorinated chains on the film surface limiting thus, the extent of their disorganization. After this study realized at a laboratory scale, we tested the photocured coating in the VCM pilot reactor. A surface cleaning, an increase of the stainless steel roughness by shot blasting and the use of alkoxysilanes as coupling agents were implemented in order to enhance the adhesion properties of the photopolymer film on stainless steel. In addition, the use of a fluorinated monomer containing a heteroatom improved the rigidification when associated with the alternated thermal/immersion post-treatment. The crust formation was limited during four successive polymerizations in the VCM pilot reactor. A durable anti-fouling UV-coating could be not obtained due to some swelling phenomena resulting from the lack of coating adhesion or some abrasion occurring from small PVC pellets during the PVC polymerization.A second part of this project was dedicated to superhydrophobic coatings. Indeed, reducing interaction with water should lead to a better protection of the substrate. A literature review on the superhydrophobic surfaces has shown that the contact with hot water generally strongly affects their antiwetting properties and induces a large contact angle decrease.

碩士<br>國立交通大學<br>應用化學研究所<br>86<br>A new silicon-containing oxirane triglycidyl phenyl silane oxide (TGPSO) and its corresponding silicon-containing epoxy resins are synthesized and characterized. The activation energies of TGPSO curing reaction with various curing agents, including 4,4-diaminodiphenylmethane (DDM), 4,4-diaminodiphenylsulfone (DDS) and dicyanodiaminde (DICY) are found to be 180, 196.5 and 154kj/mol. The curing reation of TGPSO with diamines are determined to be first order reaction through means of Arrhenius plots. The introduction of silicon-containing oxirane compared with Epon 828, Eponex 1015, and DER 732 showed relatively high char yield as well as higher limiting oxygen index (LOI = 35) than the commercial epoxy resins, confirming the usefulness of these silicon-containing epoxy resins as flame retardant. Chat yields and LOI measurements demonstrate that incorporating silicon into epoxy resins is able to improve their flame retardancy. Thermal degradation mechanism of TGPSO was studied by pyrolysis gas chromatograpy/Mass spectrometry (PGC/MS) and thermogravimetric analysis gas chromatograpy/Mass spectrometry. The most major pyrolysates of TGPSO are found to be benzene, toluene and CO2 by the PG/MS.

碩士<br>中原大學<br>醫學工程研究所<br>97<br>Silicone hydrogel contact lenses are new generation contact lenses because of its high oxygen permeability and low protein adsorption, which could increase comfort during wear. These characteristic properties are all attributed to the surface properties of silicone hydrogel. The purpose of this study was to evaluate the effects of 3-(methacryloyloxypropyl)-tris(trimethylsiloxy)silane (TRIS) on the surface properties of silicone hydrogels. In addition, polyvinyl pyrrolidone (PVP) was employed as a surface wetting agent and its effect on the surface hydrophobicity of silicone hydrogel was observed. The silicone hydrogel membrane consisted of 2-hydroxyethyl methacrylate, N,N-dimethylacryl amide, ethylene glycol dimethacrylate and TRIS monomers. In the first part of this study, it was found that the modulus increased from 0.22 MPa to 4.61 MPa as the amount of TRIS increased from 15 to 45 mol%. In addition, the oxygen permeability (DK) of the silicone hydrogel membrane increased from 60 to 110 barrers and the water content decreased from 48% to 13% given the same conditions. Based on these results, a ternary phase diagram was plotted. On the other hand, the second part of this study showed that the wetting agent PVP can notably decrease the contact angle of the membrane from 90o to 78o, bringing its value close to that of conventional contact lenses. In the third part of this study, it was found that significantly low protein adsorption on the membrane was obtained. However, increased membrane adsorption of lipid was found as the TRIS content increased. Lastly, the in vitro cytotoxicity tests showed that the silicone hydrogel and the conventional contact lenses are of the same 1 class according to ASTM F-895 standard. In conclusion, the present study reports various surface properties as a function of the composition of silicone hydrogel. This study suggests that the selection of the TRIS composition depends on a compromise between Dk and the water content of the silicone membranes. Furthermore, a surface wetting agent may be used with silicon hydrogel so as to avoid dry-eye symptom.

碩士<br>東海大學<br>環境科學與工程學系<br>104<br>Along with the advancing of modern technologies, processing of polymer wastes has become one of the most important environmental protection and resource recycling issues. Currently, for disposing polymer wastes, practitioners usually rely on landfill and incineration, while some use base-catalyst to recycle the compositions present in polymer wastes, causing secondary pollution resulting from reaction intermediate products, such as waste containing basic chemicals. This study uses acid and base as cracking catalysts for degrading waste silicone at room temperature and atmospheric pressure, then recovers the monomers and fillers from the waste silicones, and finally compares the yield of base-catalyzed and acid-catalyzed racking products, as well as the secondary pollution.

碩士<br>中原大學<br>化學工程研究所<br>100<br>In this study, the development of novel methods to synthesize monomers with benzoxazine functional groups is investigeated to overcome the disadvantage of benzoxazine by designing the molecular structure, physical, and chemical properties. The first part is to use silicon-containing poly (dimethylsiloxane - co - methylhydrosiloxane), trimethylsilyl terminated (Si-H (13000)), and phosphorus diethylphosphite (DEP), 2 - [(phenylimino) methyl] phenol (PIMP), and paraformaldhye for synthesis of monomers containing silicon or phosphorus. The samples were charaterized using Fourier transform infrared spectroscopy (FT-IR), hydrogen silicon and phosphorus spectra NMR (1H, 29Si, 31P - NMR), elemental analysis (EA), to confirm the monomer chemical structure to prove the successful synthesis of these two monomers. Then by the discussion in two parts, first part is a long-chain benzoxazine monomers containing silicon, the main chain of this monomer is silicon oxide so it has a softness and fire resistance with a benzoxazine functional groups has carries on ability of the polymerization which also can use as a modifier, then post in the mold to heat up till carry on the ring-opening reaction, this method is called “curing”. After complete polymerization, the poly (Si-H (13000)-Bz,) has the high Td5% at 332 oC and has a good spare, the mapping diagram can be found in the EDX detection dispersion is quite good. After prepares the blocks by the curing method in different weight ratio, expected that the softness and fire-resistance can increase the thermal stability of the bulk and the crispness. Experimental results show that when the BPA-FBz mixing 5wt% into Si-H(13000)-Bz, the thermal stability and LOI are improved, even if added to a 20wt%, the compatibility is also quite good. At last, all the LOI values are achieve the fire resistance standards. In Addition, the toughness of these samples has improved, when poly(Si-H(13000)-Bz) mixing 7wt% into BPA-FBz, the strain up to 8.6 percent, more than twice the original. The second part, for the phosphorus-containing monomers, with P = O groups can enhance fire resistance and also contains a benzoxazine functional groups can be polymerization to promote its physical properties, then in the DSC, can see a melting point at 70 oC and the exthermic peak at 210 oC is for ring-opneing reaction, while the DSC figure can see a wide processing range from the melting point to the ring-opening reaction point, also has excellent solubility can be soluble in common industrial solvent. After the same in a different weight ratio blend with the general benzoxazine, wish the phosphorus element can increase the fire resistance of the copolymer. The experimental results showed that its char yield and LOI values increase with the increase of the DEP-Bz content, and all the LOI value are achieve the fire standards, In addition, after the DMA detection, mixing 20wt% show the high value of glass transition temperature is 248 oC. With these result can say that mixing with DEP-Bz can increas the thermal stability and char yield, in LOI values are achieve the fire resistance standard, also can use as a modifier to add different materials which have a broad range of applications.
