ABSTRACT:
Composites comprised of reinforcing fibers in a continuous matrix of poly(biphenylene sulfide) resin and methods of producing such composites are provided. The poly(biphenylene sulfide) resin is produced by reacting 4,4'-difluorobiphenyl with an alkali metal sulfide in a polar organic compound whereby the resin has a high melting point and a high melt viscosity, and the composites formed therefrom have excellent mechanical properties and retention of mechanical properties at high temperatures.
