4-phenylenediamine hydrochloride and terephthaloyl chloride with introducing a tertiary amine in NMP-CaCl2 solvent system were studied in detail.High molecular weight PPTA with η1ah higher than 5 was prepared. Properties of this PPTA was the same as the PPTA systhesized from p-phenylenediamine with terephthaloyl chloride
