摘要:
The present invention is directed to golf balls comprising a fluid-filled center surrounded by an outer core, wherein the outer core comprises a layer formed from a low modulus HNP composition and a layer formed from a high modulus HNP composition. The present invention is not limited by which outer core layer is formed from the low modulus HNP composition and which layer is formed from the high modulus HNP composition, so long as both layers are present in the outer core of the golf ball. Low modulus HNP compositions of the present invention comprise a highly neutralized acid copolymer having a modulus of from 1,000 psi to 50,000 psi. High modulus HNP compositions of the present invention comprise a highly neutralized acid copolymer having a modulus of from 25,000 psi to 150,000 psi.

The present invention is directed to golf balls comprising a fluid-filled center surrounded by an outer core, wherein the outer core comprises a layer formed from a relatively soft HNP composition and a layer formed from a relatively hard HNP composition. The present invention is not limited by which outer core layer is formed from the relatively soft HNP composition and which layer is formed from the relatively hard HNP composition, so long as both layers are present in the outer core of the golf ball. Relatively soft HNP compositions of the present invention have a Shore D hardness of 55 or less and comprise a highly neutralized acid copolymer. Relatively hard HNP compositions of the present invention have a Shore D hardness of 45 or greater and comprise a highly neutralized acid copolymer. The material hardness of the relatively soft HNP composition is less than the material hardness of the relatively hard HNP composition.

摘要:
A golf ball is provided having a modified density gradient among the inner layers to produce a desired high or low moment of inertia and controlled spin rate is disclosed. The golf ball has three or more inner layers in addition to a cover, and the density of the inner layers is selected such that the layers inside the cover have a density progression from the core to the cover or from the cover to the core.

The present invention is directed to golf balls consisting of a multi-layer core and a cover. The multi-layer core consists of a center and an outer core layer that are both soft relative to a hard intermediate core layer. The outer core layer is preferably thin relative to the center and the outer core layer. The multi-layer core includes at least one layer formed from a low modulus HNP composition and at least one layer formed from a high modulus HNP composition.
