Abstract
Compositions of matter having among other desirable characteristics strong adhesive properties to various substrates, these compositions comprising blends of a graft copolymer of a high density polyethylene and at least one unsaturated fused ring carboxylic acid anhydride blended with a polyethylene resin of one or more homopolymers of ethylene, copolymers of ethylene and alpha-olefin, ethylene-ester copolymers and one or more elastomers such as homopolymers of isobutylene, copolymers of isobutylene with isoprene, chlorinated copolymers of isobutylene and isoprene, homopolymers of isoprene, copolymers of butadiene and styrene, block copolymers of dienes and styrene where the diene is butadiene or isoprene, homopolymers of butadiene, homopolymers of chloroprene, and copolymers of acrylonitrile and butadiene.
