  • Carboxyl modified olefinic copolymer compositions
    Patent number: 4888393
    Abstract: The invention relates to a novel low profile additive (LPA) for uncured polyester resins and the resultant molding compositions. The low profile additive is the reaction product of an ethylene/alphaolefin copolymer with a carboxylic acid or anhydride, to thereby form a non-thermoplastic carboxyl modified polyolefin. The novel LPA is a remarkably effective dimensional stabilizer and has displayed the ability to achieve net expansion in a cured polyester resin molding composition.
    Type: Grant
    Filed: May 19, 1988
    Date of Patent: December 19, 1989
    Assignee: Uniroyal Chemical Company, Inc.
    Inventors: Frank C. Cesare, William P. Whelan, Jr., Henno A. Petersen, Thomas S. Coolbaugh, Robert G. Davis
