1. A modified polyolefin blend having improved adhesion to various substrates and consisting essentially of:
- (A) about 0.1-95 parts by weight in said blend of a graft copolymer of about 70-99.999 wt.% of a high density polyethylene backbone grafted with about 30-0.001 wt.% of at least one compound containing at least one member of the group consisting of unsaturated acyclic, carbocyclic, heterocyclic, and polycyclic moieties which are fused to at least one carboxylic acid anhydride-containing ring and(B) about 99.9-5 parts by weight of a polyethylene resin selected from the class consisting of homopolymers of ethylene, copolymers of ethylene and alpha-olefin, terpolymers of ethylene, alpha-olefin and diene and mixtures of these polyethylene resins.
