  • Method for preparing a pressure sensitive adhesive formulation including an enhanced polyisobutylene modifier
    Patent number: 6982300
    Abstract: A method for preparing an improved pressure sensitive adhesive includes incorporating into a base polymer, an PIB modifier that is made up of a homopolymer of isobutylene wherein a predominant portion of the double bonds are in either an alpha position or a beta position. The modifier may function as a plasticizer, a tackifier extender or a combination plasticizer and tackifier extender for the pressure sensitive adhesive.
    Type: Grant
    Filed: July 19, 2004
    Date of Patent: January 3, 2006
    Assignee: Texas Petrochemicals LP
