    摘要: A method of making a poly(arylene sulfide/sulfone) resin comprises heating amorphous poly(arylene sulfide/sulfone) resin at an elevated temperature but below the melting temperature of the resin in a vacuum environment so that extrudate made from the resin is smooth and has reduced gas bubble content. The invention also relates to poly(arylene sulfide/sulfone) resin made in accordance with the method.

    摘要: A phenylene sulfide/sulfone polymer with relatively good melt stability and a method of producing such a polymer are provided. A previously produced phenylene sulfide/sulfone polymer is redissolved in N-methyl-2-pyrrolidone to form a solution. This solution is combined with an alcohol to precipitate highly melt stable phenylene sulfide/sulfone polymer in a particulate form. The alcohol has one to four carbon atoms, such as methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, 2-butanol, and the like and mixtures thereof.

    摘要: Poly(arylene sulfide/sulfone) polymers are treated in order to increase melt stability and decrease impurities by contacting the poly(arylene sulfide/sulfone) polymer with a soluble zinc compound and an acidic solution. In one embodiment, the polymer is treated first with the soluble zinc compound, followed by treatment with the acidic solution. In another embodiment, the polymer is treated in one step with a solution comprising a water soluble zinc compound in an acidic solution.

    摘要: 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.

    摘要: A method is provided for recovering poly(arylene sulfide) from a mixture comprising a liquid-phase poly(arylene sulfide) and a polar organic compound, wherein the liquid mixture is contacted by an amount of a liquid, vaporized, or mixed phase separation agent at least sufficient to effect or enhance a phase separation of the liquid-phase poly(arylene sulfide) component from the polar organic compound. The poly(arylene sulfide) resins recovered according to this invention generally exhibit uniform particle size and do not tend to adhere to vessel walls during the recovery.
