Abstract
The structure and physical properties of two side chain liquid crystalline polyacrylates are discussed, one bearing biphenyl core and chiral carbon atom in the flexible spacer, and the other a phenyl benzoate core. The biphenyl version displays two smectic phases of S*F and S*F types and no ferroelectric switching. The phenyl benzoate variant displays a single SC phase. The copolymerisation of the two monomers led to polymeric materials exhibiting a S*c polymorphism and composition dependent structural features. Only the copolymer of equimolar composition displayed a strong piezoelectric response in the S*F phase and ferroelectric behaviour in the lower temperature S*c modification.
