摘要

综述了液晶离聚物的分子设计与液晶热性能的关系，一般主链液晶，离子在链中浓度增加，玻璃化温度（

）和熔点（

）下降；离子在端基，对

影响不大；离子对侧链液晶的影响，取决于主链的柔顺性和离子在链中的位置等。一般情况下，无论对主链还是侧链液晶离聚物，随着离子在链中浓度增加，液晶相向各向同性液体转化温度（

）降低。

Abstract

In this paper

the relationship of molecular design and thermal properties of liquid crystalline ionomer was summarized. Usually

the existence of ionic groups in the terminal of main-chain liquid crystalline ionomers almost did not influence the

and

of the polymers.

and

decreased with increasing ionic concentration in the main-chain liquid crystalline ionomers. The influence of ions in the side-chain liquid crystalline ionomers depended on the flexibility of main chain and the ionic position in the polymer chain et al. Generally

The

decreased with increasing ionic concentration in the chain for both main-chain and side-chain liquid crystalline ionomers.
