ABSTRACT:  The polycondensation reaction of p-aminobenzoic acid with the reagent of triphenylphosphine and hexachloroethane was investigated in order to establish the optimum reaction conditions for direct polycondensation. Reaction conditions, such as the molar ratios of triphenylphosphine and hexachloroethane to the monomer, the concentrations of monomer and reagents, the reaction temperature and the kinds of acid acceptor and solvent, had considerable influence on the yield and the molecular weight of the resulting polyamide. The poly(p-benzamide) having the highest molecular weight was obtained with the molar ratio of triphenylphosphine–hexachloroethane–monomer=1.2 : 1.5 : 1.0 in the mixed solvent of tetramethylurea and pyridine at room temperature.
