Abstract

A golf ball comprising an innermost core, an outer core, and a cover is disclosed. At least a layer of the golf ball is made from a low compression, high coefficient of restitution material, and is being supported by a low deformation, high compression layer. The resulting golf ball has high coefficient of restitution at high and low impact speeds and low compression for controlled greenside play.

Claims

1. A golf ball comprising an innermost core and a cover, wherein an inner cover layer of the cover comprises a rubber composition containing a halogenated organosulfur compound, and wherein the core has a compression of greater than about 60 PGA, wherein the golf ball has a coefficient of restitution of at least 0.80 at 125 feet per second.

2. The golf ball of claim 1, wherein the halogenated organosulfur compound is pentachlorothiophenol.

3. The golf ball of claim 1, wherein the halogenated organosulfur compound is zinc salt of pentachlorothiophenol.

4. The golf ball of claim 1, wherein the cover further comprises an outer cover layer and an intermediate cover layer disposed between the outer cover layer and the inner cover layer.

5. The golf ball of claim 1, wherein the cover has a thickness of less than about 0.125 inch.

6. The golf ball of claim 5, wherein the inner cover layer has a thickness in the range of about 0.005 inch to about 0.100 inch.

7. The golf bail of claim 6, wherein the thickness of the inner cover layer is in the range of about 0.010 inch to about 0.090 inch.

8. The golf ball of claim 7, wherein the thickness of the inner cover layer is in the range of about 0.015 inch to about 0.070 inch.

9. The golf ball of claim 1, wherein the core has a diameter of at least 1.400 inches.

10. The golf ball of claim 1, wherein the compression of the core is greater than about 80 PGA.

11. The golf ball of claim 10, wherein the compression of the core is greater than about 90 PGA.
