Main chain liquid crystal thermoplastic polyesters and thermosetting epoxy resins were prepared using biphenyl mesogen. The melting point of polyesters was effectively decreased by incorporating flexible methylene spacers into the polymer main chain. The liquid crystal epoxy resins exhibit high glass transition temperature, low thermal expansion coefficient, high dielectric strength and low dielectric loss. They are suitable for the preparation of self-reinforcing molecular composites.
