  • Engineered polyolefin materials with enhanced surface durability
    Patent number: 6914094
    Abstract: An article formed from a polyolefin resin blend reaction product that includes at least one propylene-based polyolefin-metal salt and at least one property-modifying agent. Optionally, the article includes a polyethylene-based polyolefin-metal salt, thermoplastic elastomer, such as a hydrogenated styrene-butadiene random copolymer or any other styrenic block copolymer, semi-crystalline polyolefin component, or the like, or combinations thereof. Such articles have enhanced scratch and mar resistance while still retaining acceptable impact toughness. Methods of preparing articles and the blends used to form such articles are also part of the invention.
    Type: Grant
    Filed: May 16, 2003
    Date of Patent: July 5, 2005
    Assignee: Solvay Engineered Polymers, Inc.
    Inventors: Rui-dong Ding, Satchit Srinivasan
  • Ionomeric nanocomposites and articles therefrom
    Patent number: 6861481
    Abstract: An ionomeric nanocomposite that includes a base component of a propylene-based polyolefin-metal salt component and a nanostructured material. Optionally, the blend further contains a polymeric component including an ethylene ionomer, a styrenic block ionomer, a hydrogenated styrene-butadiene random copolymer, or a combination thereof. Such ionomeric nanocomposites have increased scratch and mar resistance while still retaining clarity and thermal stability. Methods of preparing such blends, as well as resultant articles including such blends, are also part of the invention.
