摘要
Abstract
A series of sulfonated polybenzimidazoles ( SPBI) was prepared via the condensation polymerization of 1,4-bis(4-carboxyphenoxy)benzene-2-sulfonate, 4,4'-dicarboxydiphenyl ether and 3 ,3'-diaminobenzidine in phosphorus pentoxide/methanesulfonic acid in a mass ratio of 1 : 10. The structures and properties of sulfonated polybenzimidazoles were confirmed by FTIR, NMR and TGA. They show good solubility in polar solvents, high thermal stability, good film forming ability and excellent mechanical properties.关键词
