| Abstract: | In this paper the aromatic-aliphatic copolyamides were synthesized from terep-hthalyl chloride (TPC), p-phenyldiamine (PPD) and aliphatic diamines (ADA. H2N-(CH2-)nNH2, n=2,6,8,10, 12) by low temperature solution polycondensation. The effects of the amount of the aliphatic diamine chain unit in copolyamides, inherent viscosity of copolyamides and temperature on the critical concentration of liquid crystalline copolyamides obtained were studied. It was confirmed that the sulfuric acid solution of these copolyamides was smectic if the aliphatic diamine unit in copolyamides was more than 16.7 mol%. |
