Golf balls that have at least one layer formed from a cationic polyurea material. In particular, the compositions of the invention, which include a polymer backbone including urea linkages with cationic groups, may be formed from an isocyanate-containing component and an isocyanate-reactive component, at least one of which includes precursor cationic groups, in the presence of an alkylating, quaternizing, or ternarizing agent.

1. A golf ball comprising at least one layer comprising a blend of a high-crystalline acid polymer and a composition comprising: a polyurea prepolymer formed from the reaction product of a diisocyanate and an amine-terminated component;wherein the prepolymer comprises a neutralizing agent comprising
1. A golf ball comprising at least one layer comprising a blend of a high-crystalline acid polymer and a composition comprising: a polyurea prepolymer formed from the reaction product of a diisocyanate and an amine-terminated component;wherein the prepolymer comprises a neutralizing agent comprising dialkyl sulfate;a curative comprising: an amine-terminated curing agent having at least one of the following general formulas: H2N—R1—NH2;R2HN—R1—NHR2;R3R2N—R1—NR2R3;H2N—R1—NHR2;R3R2N—R1—NH2; orR3R2N—R1—NHR2 where R1 comprises unsubstituted or substituted straight chain or branched aliphatic groups, unsubstituted or substituted aromatic groups, or mixtures thereof, wherein R2 and R3 independently comprise an alkyl group, an aryl group, or an aralkyl group, and wherein the amine-terminated curing agent further comprises about 5 percent to about 25 percent precursor cationic groups by weight of the amine-terminated curing agent; andwherein between about 20 percent and 70 percent of the precursor cationic groups are neutralized. 2. The golf ball of claim 1, wherein the curative further comprises a flow modifier. 3. The golf ball of claim 1, wherein the precursor cationic groups comprise a sulfide. 4. The golf ball of claim 1, wherein the golf ball comprises a core, an intermediate layer disposed about the core to form an inner ball, and a cover disposed about the inner ball, and wherein the cover is formed from the composition. 5. The golf ball of claim 4, wherein the intermediate layer is formed from a thermoplastic material. 6. The golf ball of claim 1, wherein the golf ball comprises a core, an intermediate layer disposed about the core to form an inner ball, and a cover disposed about the inner ball, and wherein the intermediate layer is formed from the composition. 7. A golf ball comprising a core and a cover, wherein the cover comprises a blend of a high-crystalline acid polymer and a composition comprising: a polyurea prepolymer formed from the reaction product of a diisocyanate and an amine terminated component;a curative comprising: an amine-terminated curing agent comprising between about 1 percent to about 50 percent precursor cationic groups by weight of the amine-terminated curing agent; andwherein the prepolymer comprises a dialkyl sulfate. 8. The golf ball of claim 7, wherein the cover comprises an inner cover layer and an outer cover layer. 9. The golf ball of claim 8, wherein the inner cover layer comprises the composition. 10. The golf ball of claim 8, wherein the outer cover layer comprises the composition. 11. The golf ball of claim 8, wherein between about 20 percent and 70 percent of the precursor cationic groups are neutralized. 12. The golf ball of claim 8, wherein the composition further comprises a flow modifier. 13. The golf ball of claim 12, wherein greater than about 70 percent of the precursor cationic groups are neutralized. 14. The golf ball of claim 8, wherein the precursor cationic groups comprise ═S. 15. The golf ball of claim 8, wherein the amine-terminated curing agent comprises between about 5 percent to about 25 percent precursor cationic groups by weight of the amine-terminated curing agent. 16. The golf ball of claim 8, wherein the composition is thermoplastic. 17. The golf ball of claim 8, wherein the composition is thermoset.
