Compositions for use in golf balls
View Patent ↗A golf ball including a core and at least one layer disposed about the core, wherein the core or the layer is formed from a composition including a base polymer, a crosslink initiator, and an additive, wherein the additive is both an inorganic-sulfur compound and a sulfuric acid amide.
1. A golf ball comprising a core and at least one layer disposed about the core, wherein the core or the layer is formed from a composition comprising a base polymer, a crosslink initiator, and an additive, wherein the additive is both an inorganic-sulfur compound and a sulfuric acid amide.
2. The golf ball of claim 1 , wherein the layer comprises the composition and the golf ball further comprises an outer cover layer.
3. The golf ball of claim 2 , wherein the outer cover layer comprises two layers.
4. The golf ball of claim 2 , wherein core comprises a thermoplastic material, a thermo set material, or a rubber-based material.
5. The golf ball of claim 1 , wherein the core comprises the composition and the layer is an outer cover layer comprising an ionomer, a polyurethane, or a polyurea.
6. The golf ball of claim 1 , wherein the core comprises the composition and the golf ball further comprises an outer cover layer disposed adjacent the layer.
7. The golf ball of claim 1 , wherein the layer comprises the composition and core comprises a rubber-based material comprising a halogenated organosulfur material.
8. The golf ball of claim 1 , wherein the golf ball further comprises an outer cover layer having a thickness of 0.01 inches to 0.05 inches and a Shore D hardness of 40 to 55.
9. The golf ball of claim 8 , wherein the outer cover layer thickness 0.015 inches to 0.35 inches.
10. The golf ball of claim 8 , wherein a moisture vapor barrier layer is disposed between the outer cover layer and the layer, the barrier layer having a vapor transmission rate of 0.45 to 0.95 (g-mm)/(m 2 -day).
11. The golf ball of claim 1 , wherein the layer comprises the composition and core comprises an ethylene-based ionomer comprising acid moieties neutralized with an organic fatty acid salt, and sufficient cation source to bring the neutralization to 100%.
12. The golf ball of claim 1 , wherein the core comprises the composition and the layer comprises an ethylene-based ionomer comprising acid moieties neutralized with an organic fatty acid salt, and sufficient cation source to bring the neutralization to 100%.
13. The golf ball of claim 1 , wherein the core comprises the composition, the layer is an intermediate layer comprising an ethylene-based ionomer comprising acid moieties neutralized with an organic fatty acid salt, and sufficient cation source to bring the neutralization to 100%, and the golf ball further comprises an outer cover layer disposed about the layer comprising an ionomer, a polyurethane, or a polyurea.
14. The golf ball of claim 1 , wherein the core has an outer diameter of 1.50 inches to 1.62 inches.
15. The golf ball of claim 14 , wherein the core has an outer diameter of 1.54 inches to 1.59 inches.
