Investigations on new achiral polymeric liquid crystalline mixtures using a pyroelectric modulation technique

In this paper we report on the synthesis and characterization of new mixtur es of achiral liquid crystalline side-chain polymers with their monomers. T he samples have a basic structure similar to materials prepared earlier sho wing antiferroelectric behaviour. They are investigated to study the influe nce of peculiar differences in the molecular structure on their physical be haviour. A laser intensity modulation technique was used to investigate the pyroelectric activity of these compounds.
