碩士 === 國立臺灣科技大學 === 化學工程系 === 103 === This work was studied on the kinetics of polymerization of N,N-bismaleimide-4,4-diphenylmethane/Barbituric acid in fixed molar ratio with Dibenzyltrithiocarbonate which used as reversible addition-fragmentation chain transfer (RAFT) agent. The system of BMI/BTA = 2/1(mol/mol) was chosen in this work. The differential scanning calorimerter (DSC) was used to measure the heat of reation for one hour at the isothermal temperature in the range of 373-403 K. The exothermic data of the reaction were calculated via Excell process and used the Matlab mathematical software to simulate the value of m with n, and then through the Arrhenius equation calculated the activation energy (Ea) and frequency factor (A). Therefore, those data could investigate the effect of kinetics of polymerization on different contents of Dibenzyltrithiocarbonate (DBTTC) in different temperature.
