摘要:
The present invention is directed to golf balls consisting of a multi-layer core and a cover. The multi-layer core consists of a small, hard center enclosed by a soft intermediate core layer and an outer core layer. The multi-layer core includes at least one layer formed from a relatively soft HNP composition and at least one layer formed from a relatively hard HNP composition.

The present invention is directed to golf balls comprising a dual-layer core and a cover. The core comprises a center having a center hardness of 50 Shore C or greater and formed from a low modulus HNP composition, and an outer core layer having a surface hardness of 75 Shore C or greater and formed from a high modulus HNP composition. Low modulus HNP compositions of the present invention have a modulus of from 1,000 psi to 50,000 psi. High modulus HNP compositions of the present invention have a modulus of from 25,000 psi to 150,000 psi. The modulus of the highly neutralized copolymer of the low modulus HNP is at least 10% less than the modulus of the highly neutralized copolymer of the high modulus HNP composition. The cover comprises an inner cover layer formed from a thermoplastic composition and an outer cover layer formed from a polyurethane or polyurea composition.

The present invention is directed to golf balls consisting of a dual-layer core and a cover. The core consists of a layer formed from a low modulus HNP composition and a layer formed from a high modulus HNP composition. The low modulus HNP composition has a material hardness of 55 Shore D or less and comprises a highly neutralized ethylene/(meth)acrylic acid/alkyl(meth)acrylate copolymer. The high modulus HNP composition has a material hardness of 45 Shore D or greater and comprises a highly neutralized ethylene/(meth)acrylic acid copolymer. The cover preferably consists of a single cover layer.

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.
摘要:
Multi-layer golf balls having a soft, low compression center; a soft, flexible outer cover layer; and a relatively hard, high compression intermediate layer disposed between the center and the outer cover layer are provided. The outer surface hardness of the intermediate layer is greater than that of both the center and the outer cover layer.

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 rubber 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 relatively soft HNP composition and at least one layer formed from a relatively hard HNP composition.
