Claims
- 1. A method of making a composite structure of components comprising:
- (a) a substrate, and adhered thereto;
- (b) an adhesive blend consisting essentially of
- (i) about 0.1-40 parts by weight in said blend of a graft copolymer of about 70-99.999 wt. % of a polyethylene backbone grafted with about 30-0.001 wt. % of at least one grafting monomer comprising at least one polymerizable ethylenically unsaturated carboxylic acid or carboxylic acid anhydride for a total of 100% and
- (ii) about 99.9-60 parts by weight of a blending resin mixture of about 25-90 wt. % of a high density polyethylene and about 75-10 wt. % of a polypropylene for a total of 100% and wherein said components are adhered together by methods including blown film coextrusion, cast film coextrusion coating, blow molding coextrusion, lamination, extrusion or coextrusion coating, powder coating, rotomolding, profile coextrusion or wire coating extrusion or coextrusion.
- 2. The method of making a composite structure of components comprising:
- (a) two or more substrates with adjacent pairs adhered together by
- (b) an intervening layer of an adhesive blend consisting essentially of
- (i) about 0.1-40 parts by weight in said blend of a graft copolymer of about 70-99.999 wt. % of a polyethylene backbone grafted with about 30-0.001 wt. % of at least one grafting monomer comprising at least one polymerizable ethylenically unsaturated carboxylic acid or carboxylic acid anhydride for a total of 100% and
- (ii) about 99.9-60 parts by weight of a blending resin mixture of about 25-90 wt. % of a high density polyethylene and about 75-10 wt. % of a polypropylene for a total of 100% and wherein said components are adhered together by methods including blown film coextrusion, cast film coextrusion coating, blow molding coextrusion, lamination, extrusion or coextrusion coating, powder coating, rotomolding, profile coextrusion or wire coating extrusion or coextrusion.
