Abstract
The present invention relates to a blend of at least one amorphous ethylene/propylene-derived copolymer, at least one non-stereoregular propylene-derived polymer having a melt viscosity of greater than about 500 Poise, and an optional tackifier that provide pressure-sensitive adhesive compositions in which a good balance of adequate adhesion to both low and relatively high surface energy substrates can be achieved.
