Patent number: 5573823Abstract: An improved pipe is produced from phenylene sulfide/biphenylene sulfide copolymers, The improved pipe has greater flexibility and ductility than pipe produced from normal PPS resin. Such pipe is produced by preparing a phenylene sulfide/biphenylene sulfide copolymer and forming the copolymer into essentially amorphous pipe by extrusion followed by rapid and uniform quench to avoid pipe crystallization, Also disclosed is a method wherein such amorphous pipe is oriented by subsequent die extrusion.Type: GrantFiled: June 30, 1992Date of Patent: November 12, 1996Assignee: Phillips Petroleum CompanyInventor: Jerry O.

Patent number: 5264176Abstract: 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.Type: GrantFiled: November 26, 1991Date of Patent: November 23, 1993Assignee: Phillips Petroleum CompanyInventors: Michael D.

Patent number: 4500706Abstract: A method of producing poly(arylene sulfide) resin suitable for the commercial production of fibers. The method includes the two stage melt filtration of a suitable poly(arylene sulfide) polymer, e.g., poly(p-phenylene sulfide), through a primary filter having an absolute micron rating of no more than about 125 microns, and through a secondary filter having a maximum absolute micron rating of about 80 or a substantially equivalent filter capacity. Also disclosed are various forms of apparatus for performing the method. In one form the apparatus employs a depth type filter of metallurgically bonded micronic size stainless steel fibers as the primary filter and one or more edge sealed screen combinations each containing one 325 mesh screen as the secondary filter.
