A series of siloxine centered side chain liquid crystal polymers have been arranged with asystematic variation in spacer length. All the polymer shown a nematic  phase, for which the nematic-isotropic transition temperature increased as the spacer length bigger. The mesogenic  group  has  syano head groups (C
