A novel method for the synthesis of liquid crystalline polymers. Preparation by the interaction of poly(acryloyl chloride) with mesogenic compounds

Abstract

Abstract A new method for the synthesis of thermotropic liquid crystalline polymers, which is comprised of the interaction of reactive polymers with mesogenic compounds, was investigated. This method is illustrated by the interaction of poly(acryloyl chloride) with p ‐hydroxybenzylidene‐ p ‐butylaniline or p ‐aminobiphenyl on the preparation of poly( p ‐acryloyloxybenzylidene‐ p ‐butylaniline and poly( N‐p ‐biphenylacrylamide)), respectively. These polymers were subjected to characterization studies which included optical microscopy, x‐ray diffraction analysis, and differential scanning calorimetry. It was established that both polymers in the melt exhibit smectic mesomorphism.
