An improved electrical cable construction is provided wherein the metallic screen is coated with a protective coating which comprises a layer of a polymer selected for its properties of high flexural modulus, high tensile strength and high melting point and an adhesive layer comprising a random, block or graft copolymer of an olefin and a polymerizable, ethylenically unsaturated carboxylic acid, acid anhydride or derivative. Optionally, the adhesive layer may comprise a blend of the copolymer and a polyolefin.

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.

Method of making a composite structure

Composite structures comprising one or more substrates and an adhesive blend adhered thereto. The blend is strongly adhesive to various substrates and especially to various polar substrates. The blend comprises a blend of a graft copolymer of a linear low density polyethylene backbone grafted with at least one grafting monomer which is one or more polymerizable ethylenically unsaturated carboxylic acids or anhydrides thereof, blended with a polyolefin blending resin. The disclosure also includes methods of adhering the blend to one or more substrates.

Composite structures

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.
