Abstract
Abstract Compositions of matter having properties that make them strong adhesives to various substrates and especially for extrusion adhesion to various polar substrates. These compositions comprise blends of a graft copolymer of a polyethylene backbone grafted with at least one grafting monomer comprising one or more polymerizable ethylenically unsaturated carboxylic acids or the anhydrides of such acids blended with a blending resin that is a mixture of one or more high density polyethylenes and one or more polypropylenes. The disclosure also includes composite structures and their method of making comprising one or more substrates and a blend of the above as the adhesive in contact with and united with the substrate or substrates.
