<正> 自从高强度高模量的Kevlar纤维作为溶致性液晶高分子问世以来,液晶高分子的研究引起了人们的极大兴趣,并受到世界各国的重视。近年来,热致液晶性芳族聚酯的研究是一个极其活跃的领域。由于其本体熔流状态呈现出排列规整的液晶性能,因此可望采用较为简单的熔融加工工艺,开发出新型高强高模的高分子材料。但由于合成复杂和价昂这些众所周知的原因,大部分仍局限于理论上的研究。本文以4,4’-(烷基二酰氧)二苯甲酰氯和4,4’-二羟基联苯为单体,采用溶液缩聚方
Abstract：The the rmotropic liquid crystal main chain aromatic polyesters were synthesized by solution polycondensation of 4,4'- (alkanedicarbonyldioxy) dibenzoyl dichlorides and 4,4'--dihydroxybipenyl. The inherent viscosity of the polymer was measured, with a Ubbelohcle viscometer. The properties of liquid crystal were chracterized comprehensively by using a polarizing microscope, a DSC instrument and X-ray diffractometre.
