主 题:odd-even effect copolyamide lyotropic phase transition
摘 要:A series of aromatic-aliphatic copolyamides containing different aliphatic diamine units was synthesized by low temperature solution *** 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.
