摘　　要：A series of aromatic-aliphatic copolyamides containing different aliphatic diamine units was synthesized by low temperature solution polycondensation.The liquid crystalline critical concentration(c^(*))and liquid crystalline critical temperature(T^(*))of these copolyamides exhibited an odd-even zigzag effect with the odd-even variation of carbon atom number in the aliphatic diamines used.

关 键 词：odd-even effect COPOLYAMIDE LYOTROPIC phase transition
