The present invention is directed to golf balls having a resilient inner core and outer core made of a material substantially free of fillers. The invention also encompasses golf balls wherein the inner and outer cores are not made of a thermoplastic material. The invention encompasses golf balls having an inner core, an outer core, an inner cover, and an outer cover wherein the inner core has a specific gravity ρ12, the outer core has a specific gravity ρ14, the inner cover has a specific gravity ρ16, and the outer cover has a specific gravity ρ18, wherein the relationship between the specific gravities is expressed by the mathematical expression: ρ16≧ρ18≧ρ14≧ρ12.

A high CoR golf ball having predetermined moment of inertia is provided. A portion of the golf ball preferably contains substantially no filler, which contributes to the increased resilience of the ball. In accordance to one aspect of the invention, the portion with substantially no filler is an intermediate layer of the ball, and preferably is the outer core layer of the ball. The remaining portions of the ball preferably contribute to the moment of inertia of the ball. To craft a low moment of inertia ball, the innermost core should have a high specific gravity. Additionally, the outermost layers of the ball may have a low specific gravity. Conversely, to craft a high moment of inertia ball, the ball should have a thin dense layer positioned radially outward from its centroid radius. Additionally, the innermost core may have a low specific gravity. To craft a mid range moment of inertia ball, the ball may comprise a high specific gravity inner core and a thin dense layer. Preferably, the portion with substantially no filler is relatively larger than other portions of the ball.

The present invention is directed to golf balls having a layer formed from a low modulus HNP composition and a layer formed from a high modulus HNP composition. Golf balls of the present invention have at least three layers, including an inner core layer, an outer core layer, a cover, and optionally an intermediate core layer. The present invention is not limited by which golf ball layers are formed from an HNP composition, so long as at least one layer is formed from a low modulus HNP composition and at least one layer is formed from a high modulus RNP composition. 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.
