Patent ID: 6991563

Claim:
A golf ball comprising a core, a thin layer having a thickness of about 0.025 mm to about 1.27 mm encasing the core, and a cover encasing the thin layer, wherein the thin layer comprises a diene polymer cross-linked with at least about 50 phr of a reactive co-agent, wherein the diene polymer is polymerized with a metallocene catalyst; wherein an elastomeric composition is disposed in the core, in the thin layer, in the cover, or between the core and the cover, wherein the composition comprises one or more materials selected from a group consisting of thermoset polymers, thermoplastic polymers, highly neutralized polymers, metallocene or single-site catalyst catalyzed polymers, polybutadienes, ethylene-propylene-diene polymers, poly(styrene-butadiene-styrene), SEBS, SEPS block polymers, styrene-ethylene block copolymers, diene polymers, and any polar group grafted or copolymerized polymers; wherein the elastomeric composition further comprises about 10 phr to about 50 phr of a second reactive co-agent.
