Synthesis of an Epoxy Resin Curing Agent Containing Maleimide Group

摘要

A novel N, N-(4-amino phenyl maleimide) diglycidyl amine (APMDGA) was synthesized from maleic anhydride, 4-nitroaniline, and epichlorohydrin by a few-step reactions via intermediate products N-(4-nitrophenyl)maleimide and N-(4-aminophenyl)maleimide. The chemical structure of APMDGA is confirmed by 1H-NMR, FT-IR, and EA. The synthesis conditions have also been investigated. The final product APMDGA shows a yellow solid, and the yield is 48.6%.
