Abstract: Golf balls including cores formed from polybutadiene reaction products having a percent change in dynamic stiffness from 0° C. to ?50° C. of less than 130 percent where the reaction products include a resilient polymer component, a crosslinking material, a cis-to-trans catalyst, and a free radical source. The golf balls may be formed with polyurethane covers, covers formed from castable reactive liquid materials, among other materials. The golf balls may also include an intermediate layer.

Abstract: The present invention is directed to golf balls having at least one layer formed from a rubber composition comprising a base rubber and from 5 to 100 parts of an oily substance, by weight per 100 parts of the base rubber. The rubber composition may be present in any one or more of a core layer, a cover layer, or an intermediate layer.

Abstract: Golf ball compositions including novel processing aids, e.g., metal salts of unsaturated fatty acids, high styrene resins, transpolyisoprene, and transpolybutadiene, for inclusion in rubber-based compositions that reduce safety risks, mixer down time, increase dispersion of the ingredients during processing, and increase component COR over that of a component formed with a conventional processing aid.

Abstract: A golf ball comprising a center comprising a polybutadiene having a molecular weight of greater than 200,000 and a resilience index of at least about 40; and a cover layer comprising a polyurethane composition formed from a prepolymer having no greater than 7.5 percent by weight unreacted isocyanate groups.

Abstract: A golf ball comprises a core, an outer cover layer, and, optionally, an intermediate layer disposed between the core and the outer cover layer. The outer cover layer may comprise a polyurethane or polyurea composition. At least one portion of the golf ball comprises a composition that enhances physical properties and/or performance characteristics (e.g., coefficient of restitution) of the golf ball. Preferably, the coefficient of restitution of the core is 0.8 or greater.

Abstract: A perimeter weighted golf ball with a low compression core is provided. The core preferably comprises a diene polymer that has low cross-link density or not cross-linked with a reactive co-agent. This core has low compression and low specific gravity. The low specific gravity core is encased within a thin dense layer positioned outside of the centroid radius to provide the ball with a high moment of inertia. The same core can be encased within a plurality of intermediate layers having either increasing hardness or decreasing hardness to provide selective golf balls for either low swing speed players or advanced players. Alternatively, a thin layer of diene polymer highly cross-linked with reactive a co-agent may be incorporated into the ball to increase the hardness of the ball.
