摘要： Hydroquinone-3,4'-biphenyl dicarboxylate polyesters, and methods of making them, are described. 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.

摘要： Fiber-reinforced terephthalate-co-4,4'-bibenzoate copolyester behaves like a liquid crystalline polymer, providing fast crystallization, short cycling times, high Tg and Tm, high strength and stiffness, while the viscosity is unexpectedly reduced at a low fiber loading ratio. In an injection molding process, the viscosity of the fiber reinforced copolyester at low fiber loading is reduced by increasing the fiber loading.
