  • Patent number: 4842947
    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.
    Type: Grant
    Filed: January 29, 1988
    Date of Patent: June 27, 1989
    Assignee: Quantum Chemical Corporation
    Inventors: Kevin V. Jachec, Peter D. Becker
  • Patent number: 4774144
    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 high molecular weight low density polyethylene having a narrow molecular weight distribution, about 0.1 to 30 wt. % of a non-elastomeric copolymer of propylene and a polymerizable, ethylenically unsaturated carboxylic acid or derivative, and the balance a non-elastomeric ethylene/propylene copolymer wherein ethylene comprises at least 5 wt. % of the copolymer.
