Abstract
Copolyimides based on 4,4'-bis(3-aminophenoxy)biphenyl (abbreviated to BAB) and pyromellitic dianhydride (PMDA) were synthesised with 4,4'-o xydianiline (4,4'-ODA) and/or 3,3',4,4'-biphenyl tetracarboxylic dianh ydride (BPDA). Basic property and melt processability of synthesised c opolyimides were investigated. Crystallisation property of these copol yimides were dependent on contents of 4,4'-ODA and/or BPDA. Melt proce ssability of copolyimides obtained from BAB, 4,4'-ODA and PMDA were de pendent on contents of 4,4'-ODA. Melt viscosities and Tg's of copolyim ides obtained from BAB, PMDA and BPDA were decreased according to incr ease of BPDA contents. (C) 1998 Elsevier Science Ltd. All rights reser ved.
