Abstract

A new series of main chain H-bonded liquid crystalline polymers were derived from binary mixtures of mesomorphic polymer (I or II) and non-mesomorphic guest molecules like suberic acid, tartaric acid and alkylated tartaric acid. The role of flexible chiral (tartaric acid and alkylated tartaric acid) and achiral (suberic) guest molecules on mesomorphism has been studied. Liquid crystalline properties of polymers and its guest acid complexes were investigated by DSC and POM analysis. The isotropic and melting temperatures of the polymers have been drastically reduced by mixing with flexible guest molecules.
