  • Hydrolysis resistant polyester compositions and related articles and methods
    Publication number: 20040034126
    Abstract: Polymer compositions comprising polyester, boron component, and epoxy component. Articles made from these compositions, particularly articles requiring excellent hydrolysis resistance properties.
    Type: Application
    Filed: April 23, 2003
    Publication date: February 19, 2004
    Inventors: William E. Garrison, James Michael McKenna
  • Flame retardant polyethylene terephthalate
    Patent number: 4708980
    Abstract: If antimony oxide is added to a blend of polyethylene terephthalate/alkali metal organic carboxylate in the form of a concentrate in a polyamide, the destabilizing effect of the antimony oxide on the blend is minimized. This greatly improves the thermal stability of the polyethylene terephthalate blend during compounding and subsequent melt processing operations, as compared with similar compositions where the antimony oxide is added in the form of a concentrate with another organic polymer, viz., polyethylene, or is added neat.
    Type: Grant

    Date of Patent: November 24, 1987
    Assignee: E. I. Du Pont de Nemours and Company
    Inventor: William E. Garrison, Jr.
  • Fast crystallizing polyester resin containing three-component crystallization system
    Patent number: 4548978
    Abstract: Fast crystallizing polyester molding composition comprising (a) a PET or PET/PBT matrix resin having an inherent viscosity of at least 0.4, (b) polyalkylene oxide soft segments incorporated into the matrix resin, (c) a plasticizer of the formula ##STR1## (d) a crystallization promoter, and (e) a reinforcing or filling material.
