Abstract
Adhesive blends especially suitable for adhesion to polypropylene and gas barrier materials are disclosed, as are composite structures incorporating such blends, and methods of making such composite structures. The blends are preferably elastomer free, and comprise a mixture of an adhesion-promoting amount of an ethylene homopolymer about 0.1 to 30 wt. % of a non-elastomeric graft copolymer of polypropylene and a graft monomer comprising a polymerizable, ethylenically unsaturated carboxylic acid or derivative, and the balance a substantially non-elastomeric ethylene/propylene copolymer wherein ethylene comprises at least 5 wt. % of the copolymer. 2
