Patent ID: 7767311

Claim:
A polymeric adhesive composition comprising: (a) a direct copolymer obtained by a high-pressure free radical polymerization process, said copolymer consisting essentially of i) a first comonomer that is an olefin; ii) from about 3 weight % to about 15 weight % of a second comonomer that is a functional comonomer selected from the group consisting of, maleic acid diesters, maleic acid monoesters, fumaric acid monoesters, and mixtures of two or more thereof; and iii) optionally, a third comonomer selected from the group consisting of vinyl acetate, esters of acrylic acids and esters of methacrylic acids; and (b) a polymeric base resin selected from the group consisting of copolymers of ethylene and an alpha-olefin, copolymers of propylene and alpha-olefin monomers other than ethylene, polypropylene homopolymers, ethylene vinyl acetate copolymers, ethylene acrylic acid copolymers, ethylene methacrylic acid copolymers, ethylene acrylic ester copolymers, ethylene methacrylic ester copolymers, salts of ethylene acrylic acid copolymers, salts of ethylene methacrylic acid copolymers, polyvinyl chloride, chlorinated polyvinyl chloride and polystyrene, and mixtures thereof, with the proviso that said base resin is not the same as said copolymer of component (a) wherein the adhesive composition comprises from about 5 to about 50 weight % of component (a) and from about 50 to about 95 weight % of component (b).
