## Abstract A series of new sideโchain cholesteric liquidโcrystalline polysiloxanes was synthesized by grafting copolymerization. The chemical structures of the obtained monomers and polymers were confirmed by Fourier transform infrared or ^1^HโNMR spectroscopy. The mesomorphic properties were inve
## Abstract The synthesis of three cholesteric monomers and sideโchain liquidโcrystalline polymers was described. The structureโproperty relationships of monomers IMโIIIM and polymers IPโIIIP were discussed. Their phase behavior and optical properties were investigated by differential scanning calo
