A series of the main chain liquid crystal polymers with X-shaped mesogens were synthesi-ed by low temperature solution polycondensation. All polymer samples had obvious thermotropic properties. Both flexible spacers and substituents had influence on the liquid-crystalline behaviour of the polymers The polymers were characterized by IR spectrometer
