| Abstract: | n present paper the aromatic-aliphatic copolyamides with different sequencestructure were synthesize from tefrphthalyl chloride (TPC),p-phenylenediamine (PPD ) and aliphatic diamine (ADA, H2N - (CH2)n -NH2,n=2, 6 ). The relationship between sequence structure of copolyamides, includingrandom degree (B) and number average sequence length (Ln), and the lyotropicliquid crystalline properties, including critical concentration (C*) and the type ofmesogenic phase was studied. The results show that the critical concentration ofthe liquid crystalline copolyamides moreses with the raise of B and decress of L.and the mesogenic pharos of copely amides transform from nematic to smectic asthe LnA / Lnp is approximately equal to 0.20. |
