摘要
采用高温溶液缩聚方法,合成了一系列不同配比的含X-型和棒型两种液晶基元的主链型芳族共聚酯。经检测,所有样品均具有热致液晶性。本文对这类共聚酯的液晶行为进行了研究。
A series of main chain type aromatic copolyesters with X-shaped and rod-shaped meso-gens were synthsized by solution polycondensations. All samples were thermotropic and the liquid-crystalline behaviour of the copolyesters was studied.
