摘要
采用界面缩聚方法合成了一系列主链型热致性液晶高分子,并用DSC和偏光显微镜方法研究了聚合物的液晶行为。
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.
