ABSTRACT:
An improved hot melt adhesive includes a base polymer and a 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 to improve the loop tack and/or the peel adhesion of the hot melt adhesive.
