What is claimed is: 1. A golf ball comprising a core and a cover, wherein at least one layer comprises a composition comprising: a prepolymer comprising a reaction product of an isocyanate and amine-terminated component, wherein the isocyanate comprises three functional groups; and a curing agent selected from the group consisting of ethylene oxide-based triamines, propylene oxide-based triamines, trimethylolpropane-based triamines, N-(2-aminoethyl)-1,3-propylene diamines, and mixtures thereof, and wherein the composition has an average molecular weight between crosslinks of about 3000 or greater. 2. The golf ball of claim 1, wherein the isocyanate is a trifunctional isocyanurate. 3. The golf ball of claim 1, wherein the amine-terminated component comprises three functional groups. 4. The golf ball of claim 1, wherein the isocyanate is selected from the group consisting of an isocyanurate trimer of hexamethylene diisocyanate, an isocyanurate trimer of toluene diisocyanate, an isocyanurate trimer of isophorone diisocyanate, a blend of isophorone diisocyanate and an isocyanurate trimer of isophorone diisocyanate, and mixtures thereof. 5. The golf ball of claim 1, wherein the prepolymer consists essentially of the trifunctional isocyanate and the amine-terminated component. 6. The golf ball of claim 1, wherein the curing agent is selected from the group consisting of ethylene oxide-based triamines, propylene oxide-based triamines, and mixtures thereof. 7. A golf ball comprising a core, an inner cover layer, and an outer cover layer, wherein the outer cover layer is formed of a composition comprising: a prepolymer, wherein the prepolymer comprises a trifunctional isocyanate and an amine-terminated component; and a curing agent selected from the group consisting of ethylene oxide-based triamines, propylene oxide-based triamines, trimethylolpropane-based triamines, N-(2-aminoethyl)-1,3-propylene diamines, and mixtures thereof, wherein the composition has an average molecular weight between crosslinks of about 3000 or greater. 8. The golf ball of claim 7, wherein the inner cover layer comprises a thermoplastic material. 9. The golf ball of claim 8, wherein the thermoplastic material comprises an ionomer resin. 10. The golf ball of claim 7, wherein the curing agent is selected from the group consisting of ethylene oxide-based triamines, propylene oxide-based triamines, and mixtures thereof. 11. The golf ball of claim 7, wherein the trifunctional isocyanate comprises a trifunctional isocyanurate. 12. A golf ball comprising a core and a cover, wherein at least one layer comprises a composition comprising: a prepolymer comprising a reaction product of an isocyanate and amine-terminated component, wherein at least one of the isocyanate or amine-terminated component comprises three functional groups; and a curing agent selected from the group consisting of ethylene oxide-based triamines, propylene oxide-based triamines, trimethylolpropane-based triamines, N-(2-aminoethyl)-1,3-propylene diamines, and mixtures thereof, and wherein the composition has an average molecular weight between crosslinks of about 3000 or greater. 13. The golf ball of claim 12, wherein the average molecular weight between crosslinks is about 4000 or greater. 14. The golf ball of claim 12, wherein the isocyanate is selected from the group consisting of an isocyanurate trimer of hexamethylene diisocyanate, an isocyanurate trimer of toluene diisocyanate, an isocyanurate trimer of isophorone diisocyanate, a blend of isophorone diisocyanate and an isocyanurate trimer of isophorone diisocyanate, and mixtures thereof. 15. The golf ball of claim 12, wherein the at least one layer is a cover layer. 16. The golf ball of claim 12, wherein the cover comprises an inner cover layer and an outer cover layer, and wherein the outer cover layer comprises the composition. 17. The golf ball of claim 16, wherein the inner cover layer comprises an ionomer resin. 18. The golf ball of claim 12, wherein the curing agent is selected from the group consisting of propylene oxide-based triamines, ethylene oxide-based triamines, and mixtures thereof. 19. The golf ball of claim 12, wherein the isocyanate comprises an isocyanurate trimer. 20. The golf ball of claim 12, wherein the average molecular weight between crosslinks is about 5000 or greater.
