摘要：

Copolyimides based on 4,4'-bis(3-aminophenoxy)biphenyl (abbreviated to BAB) and pyromellitic dianhydride (PMDA) were synthesised with 4,4'-oxydianiline (4,4'-ODA) and/or 3,3',4,4'-biphenyl tetracarboxylic dianhydride (BPDA). Basic property and melt processability of synthesised copolyimides were investigated. Crystallisation property of these copolyimides were dependent on contents of 4,4'-ODA and/or BPDA. Melt processability of copolyimides obtained from BAB, 4,4'-ODA and PMDA were dependent on contents of 4,4'-ODA. Melt viscosities and Tg's of copolyimides obtained from BAB, PMDA and BPDA were decreased according to increase of BPDA contents. (C) 1998 Elsevier Science Ltd. All rights reserved.
