Patent ID: 7767759

Claim:
A blend composition comprising the reaction product of: (A) a polymer comprising i. ethylene and/or an alpha olefin; and ii. one or more α, β-ethylenically unsaturated C 3 -C 20 carboxylic acids, sulfonic acids or phosphoric acids; wherein the polymer comprising an unsaturated C 3 -C 20 carboxylic acid comprises a high molecular weight component having a weight average molecule weight, Mw, from about 80,000 to about 500,000; (B) a compound present in an amount from about 0.1 to about 40 phr; and-having a general formula (R 2 N)—R′—(X(O) n OR y ) m , wherein i. R is selected from the group consisting of (1) hydrogen, (2) one or more C 1 -C 20 aliphatic systems, (3) one or more cycloaliphatic systems, (4) one or more aromatic systems, and (5) combinations thereof; ii R′ is a bridging group comprising (1) one or more unsubstituted C 1 -C 20 straight chain or branched aliphatic or alicyclic groups, or (2) one or more substituted straight chain or branched aliphatic or alicyclic groups, or (3) one or more aromatic groups, or (4) one or more oligomers, each containing up to 12 repeating units, and iii. when X=C or S, m is 1-3, iv. when X=C, n=1 and y=1, v. when X=S, n=2 and y=1, and (C) basic metal ion salt, which has the capacity to neutralize some or all of the acidic group present in Blend Components (A) and (B).
