The curing and decomposition kinetics for diglycidylether of bisphenol-A/di(4-aminobenzanilide)ether system

摘要

In order to prepare a high performance epoxy, we synthesized a di(3-aminobenzanilide)ether which has aromatic amide-ether amide group in the main chain as epoxy curing agent by a two-step reaction sequence. The structure of the synthesized di(4-aminobenzanilide)ether was confirmed by fourier transform-infrared (FT-IR), nuclear magnetic resonance (NMR) spectroscopy, and elemental analyzer (EA). The glass transition temperature of cured epoxy resin was 162.4 degrees C, and the thermal resistance was sustained below 330 degrees C. The curing kinetics and decomposition kinetics of cured epoxy were elucidated by Ozawa equation and Flynn-Wall equation, respectively. (C) 2000 Elsevier Science Ltd. All rights reserved.
