A new series of polymethacrylates with a chiral mesogenic pandant group linked to backbone through ethyleneoxide units of different lengths were synthesized. Mesomorphic behaviour of polymers was characterized by polariaing microscopy with hot stage
DSC and X- ray diffraction The results show that phase transition temperature and isotropic temperature depended on the length of ethyleneoxide.
