Abstract
Rubber compositions including sulfonamides, and golf ball cores made from such compositions are disclosed. The type and concentration of components in the composition affect the properties of cores made therefrom, including, for example, coefficient of restitution and compression, and, thus, can be used to produce golf balls having desirable performance characteristics.
Claims16
A golf ball having at least one layer formed from a composition comprising the reaction product of:
- a base rubber;
- from 5 phr to 50 phr of a crosslinking coagent selected from metal salts of acrylates, diacrylates, methacrylates, and dimethacrylates;
- from 0.1 phr to 5.0 phr of an organic peroxide;
- and
- from 0.1 phr to 5.0 phr of sulfanilamide;
- wherein the composition is substantially free of zinc pentachlorothiophenol.
A golf ball comprising a rubber core, the rubber core being formed from a composition comprising the reaction product of:
- a base rubber;
- from 5 phr to 50 phr of a crosslinking coagent selected from metal salts of acrylates, diacrylates, methacrylates, and dimethacrylates;
- from 0.1 phr to 2 phr of an organic peroxide;
- and
- from 0.3 phr to 1.2 phr of a COR agent selected from sulfanilamide, sulfamethoxazole, sulfacetamide, sulfisoxazole, sulfamethizole, sulfathiazole, sulfabenzamide, sulfacytine, and sulfadiazine, and combinations of two or more thereof;
- wherein the composition is substantially free of zinc pentachlorothiophenol.
A golf ball comprising an inner core layer and an outer core layer disposed about the inner core layer, wherein at least one of the inner core layer and the outer core layer is formed from a composition comprising the reaction product of:
- a base rubber;
- from 5 phr to 50 phr of a crosslinking coagent selected from metal salts of acrylates, diacrylates, methacrylates, and dimethacrylates;
- from 0.1 phr to 2 phr of an organic peroxide;
- and
- from 0.3 phr to 1.2 phr of a COR agent selected from sulfanilamide, sulfamethoxazole, sulfacetamide, sulfisoxazole, sulfamethizole, sulfathiazole, sulfabenzamide, sulfacytine, and sulfadiazine, and combinations of two or more thereof;
- wherein the composition is substantially free of zinc pentachlorothiophenol.
