摘　　要：合成了对乙酰氧基苯甲酸与聚萘二甲酸乙二醇酯的热致液晶共聚酯(简称60PHB/PEN)。通过元素分析、红外光谱、DSC、热台偏光显微镜以及广角X射线衍射对其进行了结构、液晶性表征。实验表明,合成的共聚酯确系高度无规的PEN、PHB共聚酯,在某个温度范围内呈现向列型液晶的典型特征。Thermotropic liquid crystalline copolyester 60 PHB/PEN were synthesized. The structure of copolyester was studied by element analysis and infrared Spectrum (IR) . Liquid crystalline properties were studied by DSC, polarizing microscope and X-ray diffraction. The results show that the liquid crystalline copolyester 60 PHB/PEN is nematic thermotropic liquid crystal.
