Popis:	A thorough study, devoted to analyzing the role of various reaction parameters in the direct synthesis of poly(p-phenylene terephthalamide) and poly(p-benzamide), activated by triphenyl phosphite, is described. The effects of temperature, salt type and concentration, amount of triphenyl phosphite and its stepwise introduction, as well as monomer and reagent concentrations, are considered. The inherent viscosity values of the above aromatic polyamides are higher than those reported in the literature for analogous syntheses and are comparable to the values of typical samples obtained by the acyl chloride routes. Keywords: poly(p-benzamide), poly(p-phenylene terephthalamide), triphenylphosphite, direct synthesis, aromatic polyamides.
