| Summary: | 碩士 === 國立臺灣科技大學 === 化學工程系 === 95 === The effects of nano-scale core-shell rubber type of low profile additive and Silane treated montmorillonite clay on the cure kinetics and glass transition temperature of styrene/unsaturated polyester/additive ternary system have been investigated.
The reaction kinetics of styrene/unsaturated polyester/additive ternary system during the cure at 1100C was investigated by Differential Scanning Calorimetry (DSC) and Fourier Transform Infra-Red Spectoscopy (FTIR). Adding nano-scale core-shell rubber type of low profile additive and silane treated montmorillonite clay into the system has increased the unsaturated C=C bonds conversion, which was related to the formation of microgel particles during the polymerization.
Based on the Takayanagi mechanical models, the effect of additive nano-scale core-shell rubber type of low profile additive on the glass transition temperature of ternary cured sample was studied. The glass transition temperature of the ternary cured sample was measured by Dynamic Mechanical Analysis (DMA) and Thermal Stimulated Current (TSC).
