Abstract In this work aromatic polyamides (A) and (B) having p- and m-acetoxybenzamido pendent groups were successfully synthesized by solution polycondensation reaction of various aromatic diamines, namely; m-phenylenediamine, p-phenylenediamine, 2,6-diaminopyridine, benzidine, 4,4’-oxydianiline and 4,4’-diaminodiphenylsulfone and 4,4’-methylenedianiline with the diacid chlorides 5-(4-acetoxybenzamido)isophthaloyl chloride and 5-(3-acetoxybenzamido)isophthaloyl chloride. |
