Abstract
Abstract A new aromatic diacid monomer containing pyridine unit, 4-phenyl-2,6-bis[4-(4-carboxyphenoxy) phenyl] pyridine 3 , was successfully synthesized in three steps, starting from 4-hydroxyacetophenone. The corresponding pyridine-containing polybenzimidazole was prepared via polycondensation of 3 with tetraaminodiphenyl ether (TADE) in poly(phosphoric acid) (PPA). The resulting polybenzimidazole exhibits excellent solubility, good thermal stabilities and high thermal resistance.
