Synthesis and Pyrolysis of Model Epoxide Compounds and Polymers

摘要

Six model epoxides (three crosslinked polymers, one linear polymer, and two compounds) were synthesized and their pyrolysis characteristics investigated. The techniques of thermogravimetry, differential thermometry, and infrared spectrometry were used in this research. Two of the most significant findings of this work were: (1) positions of the amine groups in three isomers of diaminobenzene, which were used as curing agents, have little effect on the thermal stability of the corresponding polymers made from m-phenylene diglycidyl ether, and (2) although m-phenylene diglycidyl ether/aminobenzene polymer is linear, it is just as stable thermally as crosslinked m-phenylene diglycidyl ether/m-diaminebenzene polymers.
