1. A golf ball comprising a core and a cover, wherein at least a portion of the golf ball is formed from a composition comprising:
- a prepolymer comprising an isocyanate and at least one of an amine-terminated component or a hydroxy-terminated component; and
a curing agent comprising an adduct formed from the reaction product of an amine and a silicone having at least one end group comprising oxirane functionality.

12. A method of forming a golf ball comprising a core and a cover, comprising the following steps:
-
providing a core; providing a precursor formed from a silicone with at least one oxirane functional endcap; forming an amine adduct by reacting an amine-terminated compound with the precursor, wherein the amine adduct comprises the precursor as the backbone; forming a prepolymer comprising; an isocyanate-containing component; and a hydroxy-terminated component, an amine-terminated component, or a combination thereof; reacting the amine adduct with the prepolymer to form a material; and forming the cover from the material. - View Dependent Claims (13, 14, 15, 16, 17, 18)
