Abstract
The present invention is directed to golf items formed from a sulfur-containing composition. The sulfur-containing composition comprises the reaction product of four reactable components: (a) polyisocyanates and polyisothiocyanates; (b) polyols and polythiols; (c) epoxides and episulfides; and (d) amines and anilines; wherein at least one of the four reactable components contains a sulfur atom. The present invention also relates to methods, e.g., reaction injection molding processes and castable molding processes, for forming such golf items.

A golf item formed from a sulfur-containing composition, the composition comprising a reaction product of four reactable components including
- a first component selected from the group consisting of polyisocyanates, polyisothiocyanates, and combinations thereof;
- a second component selected from the group consisting of polyols, polythiols, and combinations thereof;
- a third component selected from the group consisting of epoxides, episulfides, and combinations thereof;
- and
- a fourth component selected from the group consisting of amines, anilines, and combinations thereof;
- wherein at least one of the first and second components contains a sulfur atom.
A golf item formed from a sulfur-containing composition, the composition comprising a reaction product of four reactable components including
- a first component selected from the group consisting of polyisocyanates, polyisothiocyanates, and combinations thereof;
- a second component selected from the group consisting of polyols, polythiols, and combinations thereof;
- a third component selected from the group consisting of epoxides;
- and
- a fourth component selected from the group consisting of amines, anilines, and combinations thereof;
- wherein only one of the reactable components contains a sulfur atom, and
- wherein the component containing the sulfur atom is selected from the first component and the second component.
A multi-layer golf ball comprising a core, an inner cover layer, and an outer cover layer, wherein at least one of the inner cover layer and the outer cover layer is formed from a reaction injection molded material, the material comprising:
- a first component selected from the group consisting of polyisocyanates, polyisothiocyanates, and a combinations thereof;
- a second component selected from the group consisting of polyols, polythiols, and combinations thereof;
- a third component selected from the group consisting of epoxides, episulfides, and combinations thereof;
- and
- a fourth component selected from the group consisting of amines, anilines, and combinations thereof;
- wherein at least one of the first and second components contains a sulfur atom.
A method for forming a golf item comprising the steps of:
- combining at least four reactable components to form a reactive mixture, wherein the reactable components include
- a first component selected from the group consisting of polyisocyanates, polyisothiocynates, and combinations thereof;
- a second component selected from the group consisting of polyols, polythiols, and combinations thereof;
- a third component selected from the group consisting of epoxides, episulfides, and combinations thereof;
- and
- a fourth component selected from the group consisting of amines, anilines, and combinations thereof;
- wherein at least one of the first, second, third, and fourth reactable components contains a sulfur atom, and
- wherein each of the first, second, third, and fourth reactable components has a viscosity of less than about 20,000 cPs at ambient temperature or at the temperature at which the reactive mixture is formed;
- and
- injecting the reactive mixture into a cavity or mold having a desired shape, within about 60 seconds after combining the reactable components, to form a golf item.
