Abstract
The present invention is directed to a golf ball having at least one of a center, cover, or intermediate layer that includes a reaction product that includes a resilient polymer component, a free radical source, at one of a metallic mercaptothiazole and optionally one or more of a cis-to-trans catalyst, a crosslinking agent, or a filler.
Claims42
A golf ball comprising a reaction product wherein the reaction product comprises a resilient polymer component;
- a free radical source;
- and at least one of a metallic mercaptothiazole having the general formula I:
- wherein R1, R2, R3, and R4 are each independently hydrogen, unsubstituted or substituted alkyl, unsubstituted or substituted cycloalkyl, unsubstituted or substituted aryl, unsubstituted or substituted heteroaryl, unsubstituted or substituted alkoxy, alkylester, amido, amino, cyano, thioalkyl, hydroxyl, halogen, aldehyde, or alkylcarbonyl;
- and
- M is selected from the group consisting of Zn, Cu, Ni, Co, Fe, Mn, Cr, V, Ti, Cd, Pd, Rh, Ru, Mo, Nb, Zr, Mg, Ca, Sr, Ba, Ge, Sn, Pb and Bi.
A method of manufacturing golf balls comprising:
- providing a core;
- optionally providing an intermediate layer disposed outside the core;
- and
- providing at least one cover over the core and optional intermediate layer,
- wherein at least one of the cover, the core, and the optional intermediate layer comprises at least one layer formed from a reaction product wherein the reaction product comprises a resilient polymer component;
- a free radical source;
- and at least one of a metallic mercaptothiazole having the general formula I:
- wherein R1, R2, R3, and R4 are each independently hydrogen, unsubstituted or substituted alkyl, unsubstituted or substituted cycloalkyl, unsubstituted or substituted aryl, unsubstituted or substituted heteroaryl, unsubstituted or substituted alkoxy, alkylester, amido, amino, cyano, thioalkyl, hydroxyl, halogen, aldehyde, or alkylcarbonyl;
- and
- M is selected from the group consisting of Zn, Cu, Ni, Co, Fe, Mn, Cr, V, Ti, Cd, Pd, Rh, Ru, Mo, Nb, Zr, Mg, Ca, Sr, Ba, Ge, Sn, Pb and Bi.
A golf ball having at least one layer that includes a reaction product comprising a resilient polymer component having polybutadiene;
- a free radical source;
- zinc pentachlorothiophenol;
- and zinc mercaptothiazole.
