Rubber-based adhesive compositions

Abstract

Adhesive compositions including 20 wt. % to 80 wt. % of a polymer selected from the group consisting of a radial styrene-isoprene block copolymer, a radial styrene-butadiene block copolymer, and combinations thereof, and 3 wt. % to 80 wt. % of a liquid rubber having a molecular weight of 300 Daltons to 100,000 Daltons, where the liquid rubber is selected from the group consisting of an isoprene rubber, a butadiene rubber, and combinations thereof. Such adhesive compositions exhibit high cohesive integrity as well as high adhesion and peel properties.
