Abstract: The liquid crystalline properties of polysiloxane with cholesteric mesogens in sidechain and its monomer were characterized by polarized microscopy with a hot stage, DSCand x-ray diffraction.Cholesteric texture with oily streaks and spirals, monotropic smectic with fan-shaped and solid-solid transition were observed in monomer while only the smectic phase was exhibited by polysiloxane fan-shaped texture.

Key words: Liquid crystalline polymer, Polysiloxane, Cholesteryl undecylenate, Smectic phase, Cholesteric phase
