Abstract

Polystyrene-polyisoprene-polystyrene block copolymers, hot-melt adhesive compositions constituted of polystyrene-polyis-oprene-polystyrene block copolymers, and articles of manufacture produced therefrom. These copolymers possess blocks of high average molecular weight polystyrene (12,000 to 20,000) and low overall average molecular weight (60,000 to 110.000) such that when blended in requisite proportions with a compatible tackifier resin, preferably also a secondary tackifying resin or plasticiz-ing oil, and stabilizer, superior hot-melt adhesive compositions can be formed. The hot-melt adhesive compositions possess. inter-alia, superior heat resistance, superior static time to failure with low viscosity, good peel adhesion, good tack, and high ability bond to a polyethylene or polypropylene substrate at temperatures below that which may damage the substrate.
