Patent ID: 7935765

Claim:
A polymeric modifier composition consisting essentially of: (a) a first ethylene copolymer component prepared by high pressure free radical copolymerization, wherein said first ethylene copolymer (i) consists essentially of copolymerized units of ethylene and 3-15 weight % copolymerized units of a comonomer selected from the group consisting of maleic anhydride, maleic acid monoesters, maleic acid diesters, fumaric acid monoesters, and mixtures thereof, and (ii) is present in said polymeric modifier composition in an amount of from about 10 to about 50 weight % of the total weight of the polymeric modifier composition; and (b) a second ethylene copolymer component, wherein said second ethylene component consists of at least one ethylene copolymer and each ethylene copolymer consists essentially of copolymerized units of ethylene and copolymerized units of 6 to 40 weight % of a polar monomer selected from the group consisting of vinyl acetate, alkyl acrylates, alkyl methacrylates, carbon monoxide and mixtures of two or more thereof, and wherein the second ethylene copolymer component is present in said polymeric modifier composition in an amount of from about 50 to about 90 weight % of the total weight of the polymeric modifier composition.
