Golf balls containing highly-neutralized acid polymer blends
First Claim
1. A golf ball comprising:
- a core having a diameter of about 0.5 to 1.620 inches and an Atti compression no greater than about 105;
a cover layer having a material hardness between about 30 and 70 Shore D; and
an optional intermediate layer disposed between the core and the cover layer,wherein one or more of the core, the cover layer, or the intermediate layer comprises a highly-neutralized polymer blend formed from a reaction product of an acid copolymer, a metallocene-catalyzed copolymer, an olefinic block copolymer, a fatty acid or salt of a fatty acid, and a sufficient amount of a suitable cation source to neutralize the total acid content in the acid copolymer to 80% to 100%.

Abstract
A golf ball having a core, a cover layer, and an optional intermediate layer disposed between the core and the cover layer is disclosed and described. One or more of the core, the cover layer, or the intermediate layer is formed of a highly neutralized polymer blend of an acid copolymer and a metallocene-catalyzed copolymer, an olefinic block copolymer, a sufficient amount of a suitable cation source and a fatty acid or salt of a fatty acid. The highly neutralized polymer blend is neutralized from 80% to 100% while still retaining processability. Further, the core can have a diameter of 0.5 inches to about 1.62 inches and an Atti compression less than or equal to 105. The cover layer can have a material hardness between about 30 and 70 Shore D.
