摘　　要：将苯代对苯二甲酸制备成相应的二酰氯,分别与几个芳香二酚经熔融缩聚反应,得到3个芳香聚酯,聚酯的热行为分析采用DSC、热台偏光显微镜研究.结果表明:它们均为热致型液晶,具有较低的相转变温度,在普通的有机溶剂中具有良好的溶解性质.The phenyl terephthalic asid（PTA） is converted to phenyl terephthaloyl dichloride,which reacts respectively with three aromatic hydroquinones to produce three aromatic polyesters by melt polycondensation.Thermal behaviors of the polyesters are investigated by using DCS and polarizing microscope.The results show that they are all thermotropic liquid crystal and have low phase transition temperature,and they have good solubilities in common organic solvents.
