Patent ID: 8840491

Claim:
A golf ball consisting essentially of: a center having a diameter of less than 1.500 inches, a compression of 40 or less, and formed from a first polybutadiene composition, wherein the first polybutadiene composition does not include a coagent selected from the group consisting of metal salts of acrylates, diacrylates, methacrylates, and dimethacrylates; an outer cover layer; an intermediate layer disposed between the center and the outer cover layer, the intermediate layer having a thickness of from 0.005 inches to 0.100 inches, an outer surface hardness of greater than 60 Shore D, and being formed from a second polybutadiene composition comprising greater than 60 parts of a coagent selected from the group consisting of metal salts of acrylates, diacrylates, methacrylates, and dimethacrylates, by weight per 100 parts of rubber, and having a solid, single core compression of greater than 100; wherein the outer surface hardness of the center and the outer surface hardness of the outer cover layer are less than the outer surface hardness of the intermediate layer; and wherein the compression of a golf ball subassembly consisting of the center and the intermediate layer is at least 70 compression points higher than the compression of the center.
