| 摘 要： | 借酯交换反应，以对羟基苯甲酸、对苯二甲酸和双酚Ａ为单体通过淤浆聚合制备出６个低分子量芳香族热致液晶样品，即ＰＨＢＡ／ＴＰＡ／ＢＰＡ共聚酯．由于此单体含量不同的共聚酯样品在适当的溶剂中有较好的溶解性，故能进行许多表征．根据实验结果还得到了表示转变温度一组成关系的相图，并进行了讨论．

| Abstract: | amples of low molecular weight and thermotropic liquid Crystals of aromatic copolyesters are prepared by a slurry polycondensation of three monomers,i' e. p-hydrobenzoic acid, temphthalic add and bisphenol A. These copolymers obtained from the reaction of ester exchange are called as PHBA/TPA/BPA copolyesters. Many characterizahons for samples with different composihon can be carried out house of their relatiVely good solubilities in proper solvents. The phase diagram expressing the transition temperature-composition for these copolyesters is obtained and discussed. |
