THE POLYCONDENSATION OF TEREPHTHALOYL CHLORIDE AND p-PHENYLENEDIAMINE HYDROCHLORIDE IN NMP-CaCl2 SOLVENT SYSTEM*
摘要:
The solution polycondensation of 1,4-phenylenediamine hydrochloride and terephthaloyl chlo-ride with introducing a tertiary amine in NMP-CaCl2 solvent system were studied in detail.Effect of reactant concentration, the content of CaCl2, in NMP solvent and the kinds of tertiary amineon inherent viscosity of PPTA polymer have been studied. High molecular weight PPTA withinherent viscosity over 5 was obtained at 0.35Mol/L of reactant concentration in a solvent of NMP-CaCl2 with the presence of α-picoline.
