Abstract

Disclosed is an adhesive comprising an admixture of a high vinyl selectively hydrogenated block copolymer and an amorphous polyolefin. The high vinyl content of the block copolymer results in a more compatible admixture which in turn results in an adhesive that can be more easily processed than those prepared using conventional lower vinyl content block copolymers. The adhesives of the present invention can be prepared using less or even no compatibilizing additives which allows the adhesives to be used in end uses where such additives are undesirable.
