ABSTRACT:
Homogeneous blends of at least two non-crosslinked ethylene copolymers having different polar comonomer 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 copolymers can be crosslinked prior to blending in the hot melt pressure sensitive adhesive composition.
