    摘要: The present invention is directed to liquid cyrstalline polyesters which are soluble and have low melting points. Preferably the solubility in halogenated solvent is greater than 10 wt. % and the crystalline melting point is less than 125.degree. C. The polyesters are thermotropic and nematic, and preferably have a number average molecular weight from 1,000 to 25,000. The polyesters include a cyclohexane ring in the backbone and are more particularly main-chain thermotropic polyester which contain trans-1,4 cyclohexane dicarboxylate mesogens and flexible spacer groups. These compositions are useful in coating applications including floor coverings.
