  • Toughened polymer compositions
    Patent number: 7557162
    Abstract: Toughened thermoplastic compositions comprising a thermoplastic polymer toughened by the inclusion of a thermoplastic elastomer derived from a particulate rubber dynamically vulcanized in the presence of a matrix polymer. The toughened thermoplastic composition exhibits properties including toughness, improved impact resistance, and improved hardness. The compositions are utilized wherever toughened, high performance polymers are desired. A method for forming the toughened polymer compositions is also described. Processing methods, such as rotational molding, utilizing the toughened polymer compositions are described.
    Type: Grant
    Filed: January 8, 2004
    Date of Patent: July 7, 2009
    Assignee: Teknor Apex Company
    Inventors: Raman Patel, Harry Howard, Marc Caruthers, Tonya McBride, John J. Wood, III, John C. Andries
