Abstract
Golf balls including at least one non-surface layer that has been treated with a radiation source to effect a complete cure of the non-surface layer and methods for making same, wherein the radiation-curable non-surface layer includes a polymer component and, optionally, an initiator, a crosslinking agent, or both.
Claims18
A golf ball comprising a core, an intermediate layer, and a cover, wherein the intermediate layer is formed from a composition comprising:
- a polymer component having at least one ultraviolet-light curable moiety, wherein the polymer component is present in an amount of about 50 percent to about 99 percent by weight of the composition;
- and
- an initiator,
- wherein the polymer component comprises uncured ethylene copolymer rubber, uncured acrylate rubber, uncured elastomeric copolymers of a diene and an unsaturated nitrile, or combinations thereof.
A golf ball comprising a core and a cover, wherein the core comprises a center and an outer core layer, wherein the outer core layer has a hardness of about 50 Shore D or greater and is formed from a radiation-curable composition comprising:
- a polymer component having at least one ultraviolet-light curable moiety;
- and
- a photoinitiator;
- wherein the polymer component is present in an amount of 50 percent to 99 percent by weight of the composition, and comprises alkyl acrylates;

- epoxies;
- allylic glycidyl ethers;
- acyl halides;
- isocyanates;
- or mixtures thereof;
- at least one elongation promoter;
- and
- a photoinitiator,
- wherein the intermediate layer has a hardness of about 50 Shore D or greater, and
- wherein the cover is formed from a polyurethane, polyurea, or a mixture thereof.
