| 摘 要： | 本文以对苯二甲酰氯分别和五种二元酚单体,对苯二酚(HQ)、邻氯对苯二酚(CHQ)、联苯二酚(BP)、双酚A(BPA)、4,4′-二羟基二苯基甲烷(BPM)进行溶液缩聚,制备了一系列全芳族均聚酯和共聚酯,作了各种性能表征。考虑了单苯二酚和双苯二酚单体对聚合物的熔融温度、热分解温度、相变热效应、溶解性、液晶态及织态结构、液晶相范围和光学行为等影响,并讨论了二酚单体作为致介单元的分子结构条件,得到HQ、CHQ和BP为致介单体,BPA和BPA为非致介单体的结论。

| Abstract: | A series of Wholly aromatic polyesters and copolyesters were prepared from terepthalyl chloride and dihydric phenol by condensation polymerization in solution. The thermal behavior, solubility, liquid crystallinity and optical feature of these polymers are discussed. All of the results suggest that the monomers hydroquinone, chlorohydroquinone and diphenol are the mesomorphic units wheras the bisphenol A and 4,4'-dihydroxy benzyl methane are the non-mesmorphic units in the chain. |
