Abstract
Compositions of matter having properties that make them strong adhesives to various substrates and especially to various polar substrates. These compositions comprise blends of graft copolymer of a linear low density polyethylene backbone grafted with at least one grafting monomer comprising one or more of polymerizable ethylenically unsaturated carboxylic acids or the anhydrides of such acids, blended with a blending polyolefin resin. The disclosure also includes composite structures comprising one or more substrates and a blend of the above as the adhesive in contact with the substrate or substrates. The disclosure also includes the process or method that uses these blends for combining one or moe substrates.
