摘要

采用直接熔融缩聚及固相聚合方法由４

４’－二羟基二苯酮（ＢＨＰ）

对苯二甲酸（ＴＰ）

对羟基苯甲酸（ＰＨＢＡ）

间苯二酚（ＲＥＳ）成功地合成了四元共聚酯高分子

该聚酯的组成结构及性质由偏光显微镜、广角Ｘ－射线衍射、ＤＳＣ等手段进行表征

结果表明共聚酯具有向列型液晶特征．

Abstract

series of wholly aromatic thermotropic liquid crystalline copolyesters was synthesized from his (4-hydroxyphenyl) methanone

terephthalic acid

p-hydroxybenzoic acid and resorcinol via melt polycondensation and solid state polyinerization process. Under polarizing microscope with hote stage

the transition process

birefringent phenomenon and textures of samples were observed. From DSC trace

the relationship of Tg and Tm vs. monomer component were studid. WAXDmeasurements revealed that reflections at 20 = 20°and 24°were observable.All results showed that the copolyesters possessed properties of nematic random copolyesters.
