Synthesis and Functional Properties of Liquid Crystalline Polymers

Abstract

This review includes recent advances of thermotropic liquid crystalline polymers (LCP). LCPs are classified into categories in function of their molecular structure such as main chain type, side chain type and combined type LCPs. Synthesis of main chain, side chain and combined type polymers are described. Main chain type LCPs are focused on the rigid polyesters owing to their application of high performance materials. The structure of rigid polyesters and the method of depression of transition temperature are given. Various kinds of side chain type LCPs are presented and discussed their functional properties.
