It was found that the molecular weights of poly (P-phenylene terephthalamide) are increased when additives, such as pyridine and its compounds, added to the Nmethyl-2-pyrrolidone/calcium chloride solvent system in low temperature solution polycondensation of terephthaloyl dichloride and P-phenylene diamine. This paper presents experimental results regarding the different additives used, their respective amounts, the manners of adding, the contents of calcium chloride, the ratios of calcium chloride/pyridine, and monomer ratios and concentrations. An optimal reaction condition was reached when the contents of calcium chloride approaches 7--10%. A small amount of additive added increased considerably the coherent viscosity of resulting polymer.

A series of aromatic-aliphatic copolyamides with various adipoyl composition were prepared from p-phenylenediamine, terephthoyl chloride and adipoyl chloride by low temperature solution polycondensation. The liquid crystalline properties of the series of copolysmides in 100% sulfuric acid were studied. It was found that the solutions of the copolyamides with adipoyl composition below 90% (mol.) show liquid crystalline behaviour and it was determined by polarized microscopy that the critical concentration increases with adipoyl composition. It was confirmed that this lyotropic liquid crystal is nematic by small angle laser scattering, wide angle X-ray diffraction and polarized microscopy.
