摘　　要：用ＤＳＣ、ＷＡＸＤ和热台偏光显微镜等研究了热处理和外力作用对标题共聚酯液晶微观结构和序态结构的影响。The strtictures and phase transitions of thermotropic liquid crystalline aromaticcopolyesters based on p-hydroxy-benzoic acid(PHB) ,terephthalic acid(TPA)and bisphenolA(BPA) were studied by DSC,WAXD,and hot stage polarized microscopy.The effects ofannealing and shearing on the microstructures and seqtience structures of the copolyesterswere discussed emphatically,The two glass transition temperatures occurred in sample with50%PHB bave been discussed.
