Curl‐free high‐adhesion polyimide/copper laminate

Abstract
6‐Amino‐2‐(p‐aminophenyl) benzimidazole (BIA) was synthesized and empolyed as a diamine component in the preparation of polyamic acid. The mechanical and thermal properties of polyimides made from BIA as a diamine component were investigated. A highadhesion, curl‐free polyimide/copper laminate has been obtained by using BIA as a diamine component. © 1994 John Wiley & Sons, Inc.
