Synthesis and Property of Liquid Crystal Polymers Containing Photosensitive Groups

Abstract

The synthesis and free-radical polymerization of the acrylates monomer containing photosensitive chalcone group and the acrylates monomer containing mesogenic group are described in this paper. The monomers and polymers were characterized by FT-IR and 1 H NMR spectra. The thermal properties of polymers were measured by DSC and the liquid crystalline texture was measured by POM. And the results indicated that the polymers showed typical nematic phase and liquid crystal temperature range was 74 °C-103 °C.
