Golf balls comprising thermoplastic, thermoset, castable, or millable elastomer compositions are presently disclosed. The compositions comprise at least one regioselective polyisocyanate having an asymmetric structure and comprising at least a first NCO group and a second NCO group, the first NCO group being substantially more sterically interfered than the second NCO group. The first NCO group is directly attached to a tertiary carbon atom or is one methine carbon atom away from either at least one quaternary carbon atom or at least two tertiary carbon atoms. 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.

I claim: 1. A golf ball comprising at least one layer formed from a composition comprising at least one regioselective polyisocyanate, wherein the regioselective polyisocyanate has an asymmetric structure and comprises at least a first NCO group and a second NCO group, wherein the first NCO group is substantially more sterically interfered than the second NCO group, and wherein the first NCO group is directly attached to a tertiary carbon atom, or is one methine carbon atom away from either at least one quaternary carbon atom or at least two tertiary carbon atoms. 2. The golf ball of claim 1, wherein the second NCO group is at least two carbon atoms away from either at least one quaternary carbon atom or at least two tertiary carbon atoms, or is attached directly to a methylene carbon or a methine carbon. 3.

The golf ball of claim 6, wherein the regioselective polyisocyanate and the isocyanate-reactive telechelic forms a prepolymer though addition reaction between the second NCO group and the isocyanate-reactive end-groups. 8. The golf ball of claim 7, wherein the composition further comprises at least one curative having at least two isocyanate-reactive functionalities, and wherein the curative at least in part cures the prepolymer through addition reaction between the first NCO group and the isocyanate-reactive functionalities. 9. The golf ball of claim 1, wherein the layer is an inner core layer, an intermediate core layer, an outer core layer, an intermediate layer, a cover, an inner cover layer, an intermediate cover layer, an outer cover layer, a discontinuous layer, a wound layer, a foamed layer, a lattice network layer, a web or net, an adhesion or coupling layer, a barrier layer, a layer of uniformed or non-uniformed thickness, a layer having a plurality of discrete elements, or a layer filled with liquid, gel, powder, and/or gas. 10. The golf ball of claim 9, wherein the layer has a thickness of 0.125 inch or less and a Shore D hardness of 20-80. 11. A golf ball comprising at least one layer formed from a composition comprising at least one regioselective polyisocyanate, wherein the regioselective polyisocyanate comprises at least a first NCO group and a second NCO group, wherein the first NCO group is substantially more sterically interfered than the second NCO group, and wherein the regioselective polyisocyanate is selected from the group consisting of 1,4-diisocyanato-4-methylpentane, 1,5-diisocyanato-5-methylhexane, 1,6-diisocyanato-6-methylheptane, 1,5-diisocyanato-2,2,5-trimethylhexane, 1,7-diisocyanato-3,7-dimethyloctane, 3(4)-isocyanatomethyl-1-methylcyclohexyl isocyanate, 3(4)-isocyanatomethyl-1-1,3(4)-dimethylcyclohexane isocyanate, 3-isocyanatomethyl-1,2-dimethyl-3-ethyl-cyclopenlane isocyanate, 3-(2-isocyanatoethyl)-1,2,2-trimethylcyelopentane isocyanate, 4-(4-isocyanatobut-2-yl)-1-methylcyclohexyl isocyanate, and 3-(4-isocyanatobut-1-yl)-1-n-butyl-cyclohexane isocyanate.
