摘要:

以对苯二酚和对氟苯甲腈为原料, 合成了1,4-二(4-羧基苯氧基)苯, 并与4,4′-二羧基二苯醚作为共聚单体与3,3′-二氨基联苯胺反应合成了共聚型聚苯并咪唑, 通过红外光谱、核磁共振和热重分析等手段对聚合物的结构及热性能进行了分析. 研究了聚合物的黏度、溶解性、成膜性及聚合物薄膜的力学性能.

关键词: 聚苯并咪唑; 共聚型; 可溶性

Abstract:

A series of co-polybenzimidazoles were prepared via the condensation polymerization of 1,4-bis(4-carboxyphenoxy)benzene, 4,4′-dicarboxydiphenyl ether and 3,3′-diaminobenzidine in phosphorus pentoxide/methanesulfonic acid in a mass ratio of 1:10 by weight reaction medium. The structures of co-polybenzimidazoles were confirmed by FTIR and 1H NMR, and they show good solubility in polar solvents such as DMSO, DMAc and NMP, high thermal stability, good film forming ability and excellent mechanical properties.

Key words: Polybenzimidazole; Copolymer; Solubility
