  • Publication number: 20060084763
    Abstract: The present invention is a film obtained from a blend of chemically distinguishable copolymers, wherein the film has a light transmission of at least 85%, and/or a haze of less than 6%, and wherein the blend comprises a component copolymer has a secant modulus of less than 15,000 when cast independently into a film.

  • Publication number: 20060025510
    Abstract: A flame retardant polyphenylene sulfide polymeric alloy composition based on polyphenylene sulfide, a polymeric grafting agent (e.g., ethylene/n-butyl acrylate/glycidyl methacrylate terpolymer) and an ethylene copolymer (e.g., ethylene/methacrylic acid ionomer) is provided. At about 35% by weight loading with glass fibers and 13% by weight loading of brominated polystyrene (10%) and antimony oxide (3%), the composition is self extinguishing under UL-94 and retains greater than 3% elongation at break according to ASTM D638.
