Abstract: A golf ball having a core and at least one layer disposed about the core is disclosed. The at least one layer is formed from a composition having multiple reactive and/or non-reactive ingredients. At least one of these ingredients is a sterically hindered polyamine, preferably formed from an active hydrogen functional compound and an amine/acid ortho- or meta-substituted cyclic compound.

Abstract: A golf ball having a core and at least one layer disposed about the core is disclosed. The at least one layer is formed from a composition having multiple reactive and/or non-reactive ingredients. At least one of these ingredients is a telechelic polydiene polyahl having a polydispersity of 1.35 or less.

Abstract: A golf ball having a core and at least one layer disposed about the core is disclosed. The at least one layer is formed from a composition having multiple reactive and/or non-reactive ingredients. At least one of these ingredients is an isocyanate having a fused or bridge cyclic structure that is partially alicyclic and partially aromatic.

Abstract: Golf balls comprising thermoplastic, thermoset, castable, or millable elastomer compositions are presently disclosed. These elastomer compositions comprise reaction products of polyisocyanates and telechelic polymers having isocyanate-reactive end-groups such as hydroxyl groups and/or amine groups. These elastomer compositions can be used in any one or more portions of the golf balls, such as inner center, core, inner core layer, intermediate core layer, outer core layer, intermediate layer, cover, inner cover layer, intermediate cover layer, and/or outer cover layer.

Abstract: This invention is directed to a sulfur-containing composition that can be used as golf items such as golf ball components and golf equipments. 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; at least one of the four reactable components contains a sulfur atom. This invention also relates to a reaction injection molding process, a castable molding process and other methods using the sulfur-containing composition.

Abstract: A golf ball comprising a core and a cover, wherein the cover comprises a thermoplastic or thermoset composition comprising a polyurethane prepolymer or polyurea prepolymer formed from an isocyanate and a polyacrylate polyol or polyacrylate polyamine, respectively.

Abstract: A golf ball including a core, a cover, and, optionally, an intermediate layer disposed between the core and the cover, wherein at least one of the core, cover layer, or optional intermediate layer includes at least one dendritic macromolecule.

Abstract: A golf ball with a layer formed of a composite material is disclosed. The composite layer can be the outermost cover layer, an intermediate layer, or a layer of a center of the ball. The composite layer includes a filament material embedded in a matrix material. The filament material is selected such that it can sustain sufficient deformation at impact and remain elastic, i.e. essentially deforming with as little energy loss as possible. As a result, the composite cover layer contributes significantly to the resiliency of the ball and acts as a hoop-stress layer.
