Abstract:
Varnishes used for the inner coatings of food cans are mostly based on epoxy resins or vinylic organosols. The epoxy resins are produced from bisphenol A and bisphenol F and they also contain BADGE or BFDGE as stabilising components. A simple method for the quantitative determination of bisphenol A (BPA), bisphenol F (BPF), bisphenol A diglycidyl ether (BADGE), and bisphenol F diglycidyl ether (BFDGE) migrated from food packaging materials was optimised. The can sample was extracted with acetonitrile or with food simulants (distilled water, 3% acetic acid and 10% ethanol) and the extract obtained was analysed by gas chromatography coupled with mass spectrometric detector. The limits of detection and quantification ranged between 0.15&ndash;0.86 and 0.51&ndash;2.77 &micro;g/dm<sup>2</sup>, respectively. The migrating levels of bisphenols found in various can samples were for BPA and for BADGE in the range from 0.63 &times; 10<sup>&ndash;3</sup> to 0.34 mg/dm<sup>2</sup>, and from 1.49 &times; 10<sup>&ndash;3</sup> to 3.67 mg/dm<sup>2</sup>, respectively. BPF and BFDGE were practically not detected in the can samples. &nbsp;

Abstract:
Varnishes used as the inner coatings of food cans are often based on epoxy resins or vinylic organosols. The epoxy resins can be produced from bisphenol A (BPA) and bisphenol F (BPF) and they also contain bisphenol A diglycidyl ether (BADGE) of bisphenol F diglycidyl ether (BFDGE) as stabilising components. These compounds may break down during storage and also by influence of food simulants. The stability of BADGE and BFDGE was studied using reverse-phase gradient high performance liquid chromatography (RP-HPLC) with fluorescence detection (FLD). Four experiments were compared: (i) BPA solution at the concentration 3 μg/ml of each food simulant, (ii) BADGE solution at the concentration 3 μg/ml of each food simulant, (iii) BFDGE solution at the concentration 3 μg/ml of each food simulant and (iv) mixture of all bisphenols solution at the concentration 3 μg/ml of each food simulant. Distilled water, 10% ethanol, 95% ethanol and 3% acetic acid were used as food simulants. It was observed that BPA, BADGE and BFDGE were most stabile in 95% ethanol and least stabile in 3% acetic acid. Creation of hydroxy and chlorohydroxy derivatives was in each food simulant different so it cannot be predicted.

Abstract:
Abstract Liquefied products with high wood content were prepared by pretreating wood with ozone before liquefaction. As a result, the ratio of wood to polyhydric alcohol (W/P ratio) used as solvent could be increased to 2:1. Resin blends were prepared by mixing liquefied products with ethylene glycol diglycidyl ether (EGDGE, water-soluble) and diglycidyl ether of bisphenol A (DGEBA, oily consistency). The wood content of the resin blend could be increased to 53%. The resins were cured by citric acid or triethylene tetramine (TETA), and their mechanical properties were evaluated. Dynamic mechanical measurements revealed that the former had higher glass transition temperatures than the latter. It was found that the resin with DGEBA cured by citric acid had almost the same level of tensile strength as commercial plastics.

Abstract:
This study investigated the toughening effect of in situ polytriazoleketone (PTK) and polytriazolesulfone (PTS) toughening agent when applied to various epoxy resins, such as diglycidyl ether of bisphenol A (DGEBA), diglycidyl ether of bisphenol F (DGEBF), and triglycidyl p-aminophenol (TGAP) with 3,3′-diaminodiphenylsulfone as a curing agent. The fracture toughness, tensile properties, and thermal properties of the prepared epoxy samples were evaluated and compared. When PTK was mixed with DGEBF, the fracture toughness was improved by 27% with 8.6% increased tensile strength compared to the untoughened DGEBF. When PTS was mixed with TGAP, the fracture toughness was improved by 51% without decreasing tensile properties compared to the untoughened TGAP. However, when PTK or PTS was mixed with other epoxy resins, the fracture toughness decreased or improved with decreasing tensile properties. This is attributed to the poor miscibility between the solid-state monomer of PTK (4,4′-bis(propynyloxy)benzophenone (PBP)) or PTS (4,4′-sulfonylbis(propynyloxy)benzene (SPB)) and the epoxy resin, resulting in the polymerization of low molecular weight PTK or PTS in epoxy resin. Therefore, the toughening effect of PTK or PTS can be maximized by the appropriate selection of epoxy resin based on the miscibility between PBP or SPB and the resin.

Abstract:
Stereochemistry is proposed to contribute to the miscibility of poly(trimethylene terephthalate) (PTT) and bisphenol-A diglycidyl ether (BADGE), since molecular conformation is one of the determinants of the close packing ability and hence the interactions of such a system.

O foco deste trabalho foi o desenvolvimento e aplicação de microreatores enzimáticos, visando sua aplicação em sistemas de análise por injeção em fluxo. Em cima disso, dois substratos poliméricos foram utilizados para a avaliação de imobilização enzimática: um à base de poli (metil metacrilato) (PMMA) e outro em uma resina do éter diglicídico do bisfenol-A (BADGE). Uma impressora à laser de CO2 foi utilizada para confeccionar os dispositivos nas dimensões desejadas. Para o sucesso da imobilização, os sistemas foram previamente tratados com polietilenoimina (PEI) visando a introdução de grupamentos funcionais reativos na superfície dos materiais de partida. Num primeiro estudo, baseado na modificação de PMMA, a ativação do material foi conseguida após tratamento dos microcanais com PEI em meio de dimetilsulfóxido (DMSO). Já no segundo caso o tratamento com PEI envolveu a simples mistura mecânica dos materiais, objetivando a cura da resina empregada. Após a ativação dos materiais com PEI, as enzimas foram imobilizadas após passagem de uma mistura de glutaraldeído (um agente espaçador) e as enzimas. Dentre as enzimas estudadas estão a glicose oxidase (GOx), a ascorbato-oxidase (AAO), a catalase (CAT), a glutamato dehidrogenase (GDH), além de um sistema híbrido baseado na imobilização simultânea das enzimas glicose oxidase (GOx) e horseradish peroxidase (HPR). A caracterização dos sistemas desenvolvidos foi feita primordialmente por meio da espectroscopia Raman. Além disso, a aplicação de alguns dos sistemas frente a amostras reais e o cálculo de parâmetros cinéticos e operacionais dos microreatores confeccionados foram reralizados. Essas avaliações foram feitas baseadas em sistemas de detecção desenvolvidos no laboratório por técnicas eletroquímicas e por espectroscopia no visível. Como grande benefício dos sistemas desenvolvidos, podem ser destacados a velocidade e a simplicidade de implementação do processo de imobilização e operação.
The focus of this work is the development and application of enzymatic microreactors aiming their application through flow injection analysis systems. On top of that, two polymeric substrates were used for the evaluation of enzyme immobilization: one based on poly (methyl methacrylate) (PMMA) and another baed on a bisphenol-A diglycidyl ether resin (BADGE). A CO2 laser printer was used to fabricate the devices at the desired dimensions. For the success of the immobilization systems have been pretreated with polyethyleneimine (PEI) in order to introduce reactive functional groups on the surface of the starting materials. In a first study, based on PMMA modification, the activation of the material was achieved after treating microchannels with PEI in dimethylsulfoxide (DMSO). In the second case, treatment with PEI involved simply a mechanical mixture of the two materials, in order to cure the resin. After activation of materials with PEI, the enzymes were immobilized after passage of a mixture of glutaraldehyde (a spacer agent) and enzymes. Among the enzymes studied are glucose oxidase (GOx), ascorbate oxidase (AAO), catalase (CAT), dehydrogenase glutamate (GDH), and a hybrid system based on the simultaneous immobilization of the enzymes glucose oxidase (GOx) and horseradish peroxidase (HPR). The characterization of the developed systems was primarily done by Raman spectroscopy. Moreover, application of some of the proposed systems to real samples and calculation of kinetic and operational parameters are presented during the study. These evaluations were made with detection systems based on electrochemical and visible spectroscopy techniques, all developed at the laboratory. One great benefit of the developed systems, are the speed and simplicity of implementation the immobilization process and operation of the devices.

Metal can is a major food packaging material. There is usually a resin coating in the interior wall to protect metal from corrosion. However, the resin in contact with food might result in migration of its components such as bisphenol A (BPA) and the monomer of bisphenol A diglycidyl ether (BADGE). BPA belongs to a group of hor-mone disruptors. BADGE is classified as a mutagen and may readily form hydrolyzed products and chlorohydrin products in food, including bisphenol A (2.3-dihydroxypropyl) glycidyl ether (BADGE•H2O), bisphenol A bis(2,3-dihydroxy propyl) ether (BADGE•2H2O), bisphenol A (3-chloro-2-hydroxypropyl) glycidyl ether (BADGE•HCl), bisphenol A bis(3-chloro-2-hydroxypropyl) ether (BADGE•2HCl), and bisphenol A (3-chloro-2-hydroxypropyl) (2,3-dihydroxypropyl) ether (BADGE• H2O•HCl). These derivatives also have different degrees of toxicity. For monitoring the status of migration of these compounds in metal cans, we need to establish a simple, fast, and stable procedure to analyze these 7 compounds simtanenously. A quantitative method using high performance liquid chromatography (HPLC) coupled with a fluo-rescence detector was therefore developed to assay these compounds. The chroma-tographic separation was accomplished by gradient elution of acetonitrile, water and methanol on a Phenomenex Luna C18(2) column (25 cm × 4.6 mm i.d., 5 μm thickness) with a fluorescence detector at 230 nm excitation and 304 nm emission. Migration tests were performed using water, 4% acetic acid solution, 20% ethanol solution and n-heptane as food simulants in a total of 16 metal cans. The results showed that the mi-gration of BPA occurred in only 3 samples in the range of 0.002∼0.003 mg/dm2, and those of BADGE hydrolyzed products and chlorohydrin products were in the range of N.D.∼0.065 mg/dm2 and N.D.∼0.02 mg/dm2, respectively. Depending on the composition of canned drinks, these 7 compounds were ex-tracted with tert-butyl methyl ether or acetonitrile, defatted with n-hexane, cleaned up with Sep-Pak C18 and Florisil, and then analyzed by HPLC. Recovery studies were performed by spiking standard compounds into tomato juice at 0.05, 0.1 and 0.2 μg/g levels and into coffee at 0.2, 0.4 and 0.8 μg/g levels, respectively. Average recoveries in both studies were higher than 80%, and the coefficients of variation were less than 5.7%. The detection limits were 0.003 ppm for BADGE•2H2O, BADGE•H2O•HCl and BADGE•2HCl, and 0.005 ppm for BPA, BADGE, BADGE•H2O and BADGE•HCl. This method was tested in a survey of 38 canned drink samples which were purchased from markets. The results showed that the amounts of bisphenol A, BADGE and its hydro-lyzed and chlorohydrin products were in the range of N.D. ~ 0.173 ppm, N.D. ~ 2.695 ppm, and N.D. ~ 0.663 ppm, respectively, which were in conformity with the regulation of European Union.

Physical and chemical interactions and miscibility in two binary blend system: diglycidylether of bisphenol-A (DGEBA) with poly(methyl methacrylate) (PMMA) and DGEBA with polycarbonate (PC), were investigated by differential scanning calorimeter (DSC) and Fourier-transform infrared spectroscopy (FT-IR). Both blends were miscible and homogeneous. Chemical exchange reaction did not occure between DGEBA and PMMA. Chemical interactions between DGEBA and PC were proven by evidence of elevation of the glass transition temperature, shifting of the carbonyl IR absorbance peak, and enhanced solvent resistance of blends after heat treatment. In addition, effects of chemical links between polymer and epoxy on phase behavior of amine-cured epoxy/polymer blend systems were investigated by DSC, saning electron microscopy (SEM) and polarizing microscopy. Only a single Tg and a homogeneous morphology were observed in cured DGEBA/PC/DDS blend, which has been attributed to the chemical interactions between DGEBA and PC. Since chemical reaction did not occure between DGEBA and PMMA, two Tg's and segregated morphology were observed in the cured DGEBA/PMMA/DDS blend. Furthermore, equilibrium phase behavior in the blend system of PC and PMMA was investigated by dissolving both polymer into DGEBA. Upon lowering the Tg's of PC/PMMA blends and enhanced chain mobility by the plasticizing epoxy, phase separation did take place with an accelerated rate at as low as 68℃. The results suggested that the so-called "miscibility" and "LCST" between PC and PMMA was not of a thermodynamic nature.

This thesis includes five parts. In the first part, non-isothermal degradation kinetics of the cured polymer samples of N,N′-bismaleimide-4,4′-diphenylmethane (BMI)/barbituric acid (BTA) based polymers in the presence and absence of hydroquinone (HQ) were investigated by the thermogravimetric (TG) technique. By adding 5 wt% HQ into the BMI/BTA polymerization, the activation energy (E) of the thermal degradation process increased significantly in comparison with native BMI/BTA. The thermal degradation kinetics and mechanisms for the native BMI/BTA and BMI/BTA/HQ were quite different. In the second part, preparation and characterization of phenylsiloxane (PhSLX)-modified bismaleimide/barbituric acid based polymers with 3-aminopropyltriethoxysilane (APTES) as the coupling agent were investigated. The resultant hybrid polymers of BMI/BTA-APTES-PhSLX were characterized primarily by the thermogravimetric (TG) analysis in combination with differential scanning calorimetry (DSC) and Fourier transform infrared (FTIR) measurements. The thermal stability of BMI/BTA oligomer was improved significantly by incorporation of a small amount (20-30 wt%) of the copolymer of PhSLX and APTES (PASi). After adequate post-curing reactions, the PASi-modified BMI/BTA oligomers (HYBRID20 and HYBRID30 containing 20 and 30 wt% PASi, respectively) exhibited the greatly reduced thermal degradation rates in the temperature rang 300-800 oC and the increased level of residues at 800 oC as compared to the native BMI/BTA oligomer. In the third part, the thermal stability of cured samples of organofunctional polysiloxanes including glycidyloxypropyl polysiloxane (GSLX160), aminopropyl polysiloxane (ASLX160), methacryloxypropyl polysiloxane (MSLX160) and vinyl polysiloxane (VSLX160) was investigated. The result showed that these ogranofunctional polysiloxanes showed very different weight loss-vs.-T profiles. As to VSLX160, the weight loss only decreased gradually beyond 450 oC, indicating its superior thermal stability as compared to other polysiloxanes. Thermal degradation was not observed in FTIR measurements for GSLX160, MSLX160 and VSLX160 subjected to thermal treatment at 300 oC over a period of 1 h. By contrast, the amino group-containing ASLX160 underwent degradation when it was treated at 300 oC for 1 h. These results showed that ASLX160 exhibited the worst thermal stability as compared to GSLX160, MSLX160 and VSLX160. The thermal degradation kinetics for GSLX160, ASLX160 and MSL160 were determined by the model-fitting method with the aid of a deconvolution technique. The degradation mechanisms determined for all organofunctional polysiloxanes were quite different. In the fourth part, non-isothermal radical polymerization kinetics for BTA/bisphenol A diglycidyl ether diacrylate (EA) and benzoyl peroxide (BPO)/EA (serving as the reference) in N-methyl-2-pyrrolidone (NMP) were investigated. The DSC data showed that the activation energy of the polymerization of EA initiated by BTA was much lower than that initiated by BPO. For polymerizations of BTA/EA and BPO/EA except BPO/EA = 3/100 (w/w), the reaction mechanism involving nucleation, followed by nucleus growth in the first stage was proposed. For the polymerization of BPO/EA [3/100 (w/w)], the reaction system was adequately described by the instantaneous nucleation and nucleus growth mechanisms in the first stage. Moreover, the nucleation and subsequent growth of microgel nuclei were primarily governed by the propagation reaction and diffusion-controlled termination reaction for the polymerization system of BTA/EA or BPO/EA. In the second stage (in the conversion range 0.75-0.9), the diffusion-controlled propagation and termination reactions governed the development of highly crosslinked macrogel (i.e., macroscopic agglomerate). Finally, non-isothermal degradation kinetics of cured polymer samples of BTA/EA and BPO/EA was studied. The cured polymer sample of BTA/EA exhibited an inferior thermal stability as compared to the BPO/EA counterpart (as the reference). The degradation kinetics for cured polymer samples of BTA/EA and BPO/EA were determined by the model-fitting method with the aid of a deconvolution technique. For the cured polymer sample of BTA/EA, the complex degradation process was described by the diffusion-controlled and reaction-controlled mechanisms in the first and second steps, respectively. For the sample of BPO/EA, the mechanism responsible for the first step of the degradation process was reaction-controlled. By contrast, the degradation process was described by the nucleation-controlled mechanism, followed by the multi-molecular decay law in the second step. The different degradation kinetics and mechanisms between cured polymer samples of BTA/EA and BPO/EA were attributed to their different crosslinked network structures.

Abstract:
Layered silicate nanolayers can be used as alternative inorganic components for the construction of nanostructured hybrid composites. The clay silicate nanolayers possess stable Si-O bonds and high particle aspect ratios comparable to conventional fibers. Their interlayer surface is easily modified by ion-exchange reaction, and the gallery can be intercalated by organic polymer precursors for the formation of organic-inorganic nanocomposites. Exfoliated clay composites contain single, 1 nm thick layers of clay dispersed in the polymer matrix. Owing to the platy morphology of the silicate layers, exfoliated clay nanocomposites can exhibit dramatically improved properties such as barrier and mechanical properties that are not available for conventional composite materials. Since the clay particles scavenge water, the nanocomposite samples initially absorb slightly higher amounts of water in comparison to the no-clay samples, with the water molecules congregating around the clay particles. On the other hand, the presence of these clay particles still hinders diffusion of water through the sample, thus protecting the structural interfaces. In this work, low viscosity liquid aromatic diglycidyl ether of bisphenol A (DGEBA) epoxy resin Epon 815C was mixed with nanoclay at 60°C for 6 hours. The epoxy-clay mixture was then mixed with curing agent DETA (Diethylenetriamine) at 80°C for 4 minutes and cured at 120°C for 3 hours to produce exfoliated clay — epoxy resin system. These samples were used to first optimize the percent clay level for lowest water uptake, and subsequently immersed in water in stressed condition (flexural stress) to assess the effect of stress on nanocomposite epoxy system for its water uptake behavior. The results revealed up to 33% reduction in water uptake for the stressed samples.

Abstract:
Polymer nano-composites (PNC) are polymers which are reinforced with less than 5% by volume of nano-sized particles with high aspect ratios (L/h > 300). Compared to conventional composites, where the reinforcement is on the order of microns, the nano-composites are reinforced on the order of a few nanometers with advantages in processing and toughness. Nano-composites of epoxy clay have been studied where epoxy is mixed at high shear rates with clay. In our method of making nano-composites, an epoxy, Diglycidyl ether of bisphenol (DGEBA) A was mixed under high shear with organically modified mica type silicate (OMTS) either of benzyl dimethyl stearyl ammonium (BDSMA) or of methyl bishydroxyethyl stearyl ammonium chloride ion exchange with sodium montmorillonite. Nano-composites of epoxy cured with hexahydrophthalic anhydride (70%) with polyether polyol (25%) were made also under high shear both at 90C and 120C. Heat of reaction and transition temperature of epoxy nano-composite was compared with cured epoxy nano-composite. Analysis by X-Ray Diffraction was used to determine peaks, spacing and interfacial region. Dynamic visco-elastic measurements were used to distinguish between the nano-composites from two organically modified mica type silicates. Effect of increase in concentration and temperature on visco-elastic modulus of nano-composites was analyzed in terms of intercalation of polymer chains.

Abstract:
Results are reported from an ongoing experimental investigation of the effects of thermo-oxidative aging on the mechanical behavior of an epoxy shape memory polymer (SMP). Chemo-rheological degradation due to macromolecular scission and cross-linking is one of the main factors contributing to the chemical aging of thermo-responsive SMPs. This aging may manifest as residual strain or irreversible material property changes, which can affect the performance and limit the useful life of a SMP. A relatively new epoxy SMP based on the diglycidyl ether of bisphenol A is synthesized, and specimens are tested under uni-axial tension using a dynamic mechanical analyzer. Fundamental viscoelastic behavior and thermal expansion coefficients are first characterized, showing a glass transition near 60 °C. Shape memory cycle experiments are performed at shape fixing temperatures of 80, 125, 150 and 175 °C, and the effect of fixing time at each temperature is examined upon subsequent strain recovery at 80 °C. Performance parameters such as recovery ratio, speed of recovery and residual strain are quantified as a function of shape fixing time and temperature. No effect of chemical aging was seen at a fixing temperature of 80 °C, although the recovery ratio decreases initially with increasing fixing time and stabilizes near 92 %. Only minor effects of chemical aging are seen in the mechanical responses for fixing temperatures of 125 and 150 °C, but specimens exhibit progressively more noticeable color changes that indicate oxidation. Significant effects are observed at the highest fixing temperature of 175 °C, where chemical aging at longer fixing times results in a reduction in recovery rate across the rubber-glass transition temperature, progressively larger residual strains, lack of complete strain recovery at 80 °C, and higher temperatures to achieve 90 % strain recovery.
