ABSTRACT OF THE DISCLOSURE Homogeneous blends of at least two non-cross- linked ethylene copolymers having different polar comon- omer contents are mildly crosslinked to reduce their melt index. The crosslinked blend can be mixed with tackifier, plasticizer, filler and antioxidant to yield hot melt pressure sensitive adhesive compositions. In the alternative, at least one of the two ethylene copoly- mers can be crosslinked prior to blending in the hot melt pressure sensitive adhesive composition.
