Abstract

Golf balls comprising elastomer compositions are presently disclosed. These elastomer compositions comprise at least one polyamine having the structure:

where R₁ and R₂ are the same or different radicals chosen from hydrogen and C₁-C₆₀ organic moieties: Z₁ is chosen from halogens and C₁-C₆₀ organic radicals: and Z₂, Z₃ and Z₄ are the same or different radicals chosen from hydrogen, halogens, and C₁-C₆₀ organic radicals. These elastomer compositions can be used in any one or more portions of the golf balls, such as inner core layer, intermediate core layer, outer core layer, intermediate layer, cover, inner cover layer, intermediate cover layer, and/or outer cover layer.

Claims

1. A golf ball comprising a core and at least one layer disposed about the core, wherein the layer comprises a material formed from a composition comprising at least one polyamine having a structure of:

2. The golf ball of claim 1, wherein the layer is an outer cover layer.

3. The golf ball of claim 1, wherein the layer is an intermediate layer between the core and an outer cover layer.

4. The golf ball of claim 1, wherein the layer has a thickness of 0.005 inches to 0.125 inches.

5. The golf ball of claim 1, wherein the layer has a Shore D hardness of 20 to 80.

6. A golf ball comprising a core and at least one layer disposed about the core, wherein the layer comprises a material formed from a composition comprising at least one polvamine having a structure of:

7. The golf ball of claim 6, wherein the polyamine has one of the following structures:
