6-Amino-2-(p-aminophenyl) benzimidazole (BIA) was synthesized and empl
oyed as a diamine component in the preparation of polyamic acid. The m
echanical and thermal properties of polyimides made from BIA as a diam
ine component were investigated. A high-adhesion, curl-free polyimide/
copper laminate has been obtained by using BIA as a diamine component.
