Synthesis of a number of cholesteric polymer liquid crystals (PLCs) is reported. Phase behavior and structures of thermotropic cholesteric PLCs are discussed. Optical properties of such materials are reported also, including their textures, effects of composition variation on the helix twisting power and temperature dependence of the helix pitch. Effects of molecular mass variation on the optical properties of PLCs are determined. Prospects of applications of these materials are pointed out.
