Patent ID: 7766767

Claim:
A golf ball consisting of: (a) a center having a diameter of from 0.750 inches to 1.250 inches and formed from low modulus HNP composition, the low modulus HNP composition comprising: a highly neutralized ethylene/(meth)acrylic acid/alkyl(meth)acrylate copolymer having a modulus of from 1,000 psi to 50,000 psi; (b) an outer core layer having a thickness of from 0.150 inches to 0.400 inches and formed from a high modulus HNP composition, the high modulus HNP composition comprising: a highly neutralized ethylene/(meth)acrylic acid copolymer having a modulus of from 25,000 psi to 150,000 psi; and (c) a cover layer having a thickness of from 0.025 inches to 0.075 inches and a surface hardness of 64 Shore D or less; wherein the modulus of the highly neutralized copolymer of the low modulus HNP composition is at least 10% less than the modulus of the highly neutralized copolymer of the high modulus HNP composition.
