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

    Abstract: Melt stable polymeric resins are provided by process which comprises heating a first particulate resin selected from the group consisting of poly(arylene sulfide ketone) and poly(arylene sulfide diketone), while in the presence of a gaseous oxidizing atmosphere, to a temperature at least about 150.degree. C. (302.degree. F.) but below the melting point of the first particulate resins, for time sufficient to produce a second particulate resin. The thermal stability of the second particulate resin is superior to that of its respective first particulate resin is superior to that of its respective first particulate resin. Moreover, the molecular weight of the second particulate resin is greater than that of its respective first particulate resin.
