Patent ID: 6896628

Claim:
A golf ball comprising: a core; a cover comprising a blend of an ionomeric polymer of at least one moderately high modulus ionomer; and, at least one moderately low modulus polymer having a Shore D hardness of about 45-67, wherein said blend comprises about 20 to 45% by weight of said moderately low modulus polymer and said blend is disposed over said core, wherein the moderately high modulus ionomer is a copolymer consisting of approximately 80-90% by weight of an olefin, 10-20% by weight of unsaturated carboxylic acid wherein 10-90% of an acid groups formed are neutralized by an ion donor, wherein the olefin of the moderately high modulus ionomer is ethylene, wherein the unsaturated carboxylic acid is methacrylic acid and the acid groups are neutralized by the ion donor selected from the group consisting of sodium, zinc, magnesium and lithium ions or mixtures thereof, and wherein said moderately high modulus ionomer has a melt index of 0.5 to 1.0 grams/10 minutes, a flexural modulus of about 30,000 to 75,000 PSI, and a shore D hardness of about 55-75; wherein the moderately low modulus polymer comprises approximately 79-90% by weight of an olefin, 10-21% by weight of unsaturated carboxylic acid, wherein said moderately low modulus polymer is ethylene, wherein said unsaturated carboxylic acid is methacrylic acid and has a melt index of 10 to 65 grams/10 minutes, a flexural modulus of about 10,000 to 14,000 PSI.
