  • Process for producing poly(arylene sulfide)
    Patent number: 6331608
    Abstract: A process is provided to recover at least one modifier compound and at least one polar organic compound from a reaction mixture comprising high molecular weight Poly(arylene sulfide) product, low molecular weight P(AS), cyclic and linear P(AS) oligomers, at least one POC, at least one modifier, an alkali metal halide by-product, and water.
    Type: Grant
    Filed: September 13, 1999
    Date of Patent: December 18, 2001
    Assignee: Phillips Petroleum Company
    Inventors: Fernando C. Vidaurri, Jon F. Geibel, James W. Waterman, Jay M. Chaffin, Aubrey South, Jr., Jeffrey S. Fodor, Glenn F. Kile
  • Process for producing poly (arylene sulfide)
    Patent number: 6201097
    Abstract: A novel treatment and recovery process is provided which produces commercially desirable high molecular weight poly(arylene sulfide)s from undesirable low molecular weight poly(arylene sulfide)s. The novel process reduces the quantity of low molecular weight poly(arylene sulfide)s which otherwise have little or no commercial value and can require disposal.
    Type: Grant
    Filed: December 31, 1998
    Date of Patent: March 13, 2001
    Assignee: Phillips Petroleum Company
    Inventors: Jon F. Geibel, Fernando C Vidaurri, Jr., Glenn F. Kile
  • Production of granular poly(arylene sulfide) polymers containing reduced amounts of oligomers
    Patent number: 5374709
    Abstract: A method for removing oligomers and non-polymeric impurities from poly(arylene sulfide) polymers and producing the polymers in easily recoverable granular form is provided in which a poly(arylene sulfide) polymer associated with oligomers and non-polymeric impurities is contacted with a solvent, water, and optionally, a base, at a sufficient temperature to substantially dissolve the polymer, oligomers and impurities; then the solution is cooled to a temperature at which the poly(arylene sulfide) precipitates while oligomers and impurities remain in solution, then the precipitated polymer is separated from the solution containing the oligomers and impurities. A polymer product produced by this method is also disclosed.
    Type: Grant
    Filed: October 23, 1992
