主 题:Polybenzimidazoles Pyridine-containing diacid monomer Synthesis Thermal stabilities
摘 要: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 *** 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.
