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

In order to prepare a high performance epoxy, we synthesized a di(3-aminobe nzanilide)ether which has aromatic amide-ether amide group in the main chai n as epoxy curing agent by a two-step reaction sequence. The structure of t he synthesized di(4-aminobenzanilide)ether was confirmed by fourier transfo rm-infrared (FT-IR), nuclear magnetic resonance (NMR) spectroscopy, and ele mental analyzer (EA). The glass transition temperature of cured epoxy resin was 162.4 degrees C, and the thermal resistance was sustained below 330 de grees C. The curing kinetics and decomposition kinetics of cured epoxy were elucidated by Ozawa equation and Flynn-Wall equation, respectively. (C) 20 00 Elsevier Science Ltd. All rights reserved.
