| 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 sulfo-nated 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. |
