Abstract:

The research programme studied the cure reaction of a phenolic novolak resin and the effects of various additives and fillers on the reaction. The programme utilised the recently developed thermal analysis technique of temperature-modulated differential scanning calorimetry (TMDSC) performed in conjunction with other available thermal analysis techniques. TMDSC enables the signal for the heat of reaction to be separated from the underlying specific heat change in the resin. This meant that the reaction could be studied without interference from any physical changes in the resin.

Abstract:

Materiais de fricção são compósitos cuja matriz polimérica é, usualmente, a resina fenólica novolaca. Os requisitos de desempenho dos materiais de fricção demandam um rígido controle das condições de processamento, na formação de ligações cruzadas da resina fenólica de hexametilenotetramina (HMTA), que definem as propriedades do produto final. Nesta dissertação, resinas fenólicas novolaca pó, com teores de 7, 9 e 11% do agente de cura hexametilenotetramina (HMTA), foram caracterizadas quanto ao peso molecular, além da determinação do comportamento térmico e reológico, objetivando sua aplicação

Abstract:

The chemical modification of low molecular weight novolac oligomers and siloxane/silane-containing monomers has led to novel phthalonitrile derivatives with low glass transition temperatures, ranging from -25 to 75 ºC. Multi-functional, low molecular weight phenol-formaldehyde novolac resins were blended with these novel phthalonitrile derivatives to achieve low viscosity resin blends. Moderate temperatures and rapid curing cycles were employed (200 ºC, 1 h and 225 ºC, 4h) to produce networks with high glass transition temperatures (> 250 ºC).

Abstract:

Void-free phenolic networks have been prepared by the reaction of phenolic novolac resins with various diepoxides. The stoichiometric ratio can be adjusted to achieve networks with good mechanical properties while maintaining excellent flame retardance. A series of linear, controlled molecular weight, 2,6-dimethylphenol endcapped cresol novolac resins have been synthesized and characterized. The molecular weight control was achieved by adjusting the stoichiometric ratio of cresol to 2,6-dimethylphenol and using an excess of formaldehyde. A dynamic equilibrium reaction was proposed to occur

Without specialized treatment, some enzymes tend to lose their activity when stored on microPADs within 48 hours, which is a major hurdle for taking these types of devices out of the laboratory and into the real world.

碩士<br>國立清華大學<br>化學工程學系<br>89<br>In this study, modified novolac type epoxy resin has been used as a new matrix precursor to fabricate C/C composites. The polydimethylsiloxane polyurethane synthesized was used as a modification agent. Novolac type epoxy has almost the same chemical structure as phenolic resin, however, it possesses the epoxied functional group that is easy to react with the modification agent. The modification system utilized is polydimethylsiloxane polyurethane(PDMS-PU) which protects the fiber surface and improves the thermal stability of matrix. PDMS-PU was synthe

Effects of polydimethylsiloxane on the physical, chemical, mechanical and thermal properties of nanocomposite material were discussed. The polydimethylsiloxanes with various molecular weights (MW = 400~700) were used. Moreover, due to the incompatibility of polydimethylsiloxane and GPTS modified novolac type phenolic resin, three coupl

CCL made by 3 stages as show blow. Stage A, the glass fiber is coated by epoxy slurry, which contains monomer、initiator、curing agent and solvent. Stage B, the coated glass fiber is cooked until preprag formation. Stage C, the preprag is covered with copper foil and post cured under pressure and degas.

Abstract:

The phenolic resin chemistry is an old chemistry that started in the late 1800’s. A lot of research work to gain understanding of phenolic resins has been done and reported in literature. However, most of the studies are based on phenol novolac resins. It was necessary to acquire more knowledge on specifically o-cresol novolac (OCN) resins because of the interest in the production of these resins. The chemistry in question was new to Sasol and one of the major objectives of doing this work was to build in-house competency in this field. This was achieved by first investigating whether the avai
