  • Liquid crystalline polyester compositions and methods
    Patent number: 10759900
    Abstract: Liquid crystalline hydroquinone-3,4?-biphenyl dicarboxylate polyesters, and methods of making them. The polyesters may be melt processed at a temperature below the thermal decomposition temperature and the isotropic temperature, and may form a liquid crystalline glass phase. The polyesters may be formed by polycondensation of hydroquinone or a hydroquinone derivative with 3,4?-biphenyl dicarboxylic acid.
