Abstract: An aromatic sulfide/ketone polymer is prepared from a dihaloaromatic ketone, alkali metal sulfide, water and a polar organic compound. The polymerization reaction mixture is subjected to a heat soak at an elevated temperature, then a separation agent is added under controlled conditions and the mixture is subsequently cooled to provide a mixture comprising particulate aromatic sulfide/ketone polymer. Biaxially-oriented film is made from the recovered particles of aromatic sulfide/ketone polymer by (1) washing the polymer particles with an aqueous calcium salt, (2) heating the washed particles to remove water, (3) molding the heated particles to form a sheet of polymer, (4) biaxially stretching the sheet above the glass transition temperature of the polymer to form a film, and (5) heat-setting the biaxially-oriented film under stretching tension for a time and at a temperature to increase strength properties and density.

Abstract: A process to form a fiber-reinforced composite having a continuous thermoplastic matrix of poly(arylene sulfide ketone) resins is provided. The composite is useful to form shaped articles with high temperature resistance. The composite can be prepared by consolidating under heating a multi-layer stack of resin sheets and fiber reinforcement sheets. The poly(arylene sulfide ketone) resins can be melt-stabilized through treatment with a water-soluble salt of an alkaline earth metal. The composite has excellent thermal properties such as heat distortion temperature.
