  • LOW GLOSS ABS COMPOSITIONS
    Publication number: 20110117305
    Abstract: This invention relates to a mass polymerized rubber-modified monovinylidene aromatic copolymer composition compositions with an improved balance of aesthetic, physical and mechanical properties, in particular, a combination of low gloss and good impact resistance in (co)extruded sheet and thermoformed/vacuum formed articles therefrom. A method for preparing such compositions and articles is disclosed. The improved gloss performance is achieved by maintaining the following relationship between the average rubber particle size (RPS) and the weight average molecular weight (Mw) of the matrix polymer: Mw?155?10?6*RPS6.

  • Polyolefin barrier films for preventing solvent attack on plastic resins
    Patent number: 5338601
    Abstract: This invention relates to the use of a barrier film, being a thermoplastic linear polyolefin resin, to protect a styrenic resin sheet which constitutes the inner liner wall of an insulative cabinet wall of, for example, a refrigeration appliance unit from attack by the halogen-containing blowing agents present in the insulative polyurethane foam found within the cabinet wall. Preferred thermoplastic linear polyolefin resins are linear low density polyethylene.
    Type: Grant

    Assignee: The Dow Chemical Company
    Inventors: Jan Brands, Henri J. M. Grunbauer, Kees-Jeen van Duin
  • Barrier films for preventing solvent attack on plastic resins
    Patent number: 5227245
    Abstract: This invention relates to the use of a barrier film consisting essentially of thermoplastic homo- or copolymer polyester resin to protect a styrenic resin sheet which constitutes the inner liner wall of an insulative cabinet wall of, for example, a refrigeration appliance unit from attack by the halogen-containing blowing agents present in the insulative polyurethane foam found within the cabinet wall.
