Abstract
Hot melt pressure sensitive adhesives are formulated using as a base resin a mixture of a styrene-isoprene-styrene block copolymer together with a specific selectively hydrogenated block copolymer within critically defined ratios. The resultant adhesives as well as the tapes coated therewith are characterized by a unique combination of adhesion and heat and oxidative resistance properties.
