  • Rubber-acrylic adhesive formulation
    Patent number: 6670417
    Abstract: Pressure sensitive adhesive formulations of an acrylic polymer grafted with a hydrogenated rubber. In one embodiment, the polymer contains a hydroxyalkyl (meth)acrylate ester which is crosslinked with a titanium-containing chelated metal alkoxide. The adhesive formulations provide an exceptional combination of adhesion to low energy surfaces and high temperature cohesive strength.
    Type: Grant
    Filed: February 13, 2003
    Date of Patent: December 30, 2003
    Assignee: National Starch and Chemical Investment Holding Corporation
    Inventors: Paul B. Foreman, Smita M. Shah, Rama Chandran, Patrick S. Eaton
