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.

Fiber-reinforced poly(biphenylene sulfide) composites and methods

Novel metal-working process and aqueous metal-working fluids are provided. The aqueous metal-working fluids contain at least one sodium hydrocarbylthiocarboxylate as an extreme pressure (EP) additive.

Aqueous metal-working composition and process

Improved poly(arylene sulfide sulfone)s are prepared by contacting these polymers with a zinc source, optionally first with an alkali metal base, for a period of time sufficient to incorporate enough zinc cations to improve the melt stability of the polymers. The polymer can be subsequently cured to increase molecular weight.
