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.

Abstract: A golf ball comprising a core, a cover, and optionally an intermediate layer between the core and the cover, wherein a stable free radical is incorporated into at least one portion of the core, the cover, and the optional intermediate layer.

Abstract: A golf ball comprising a solid core and a cover disposed about the core, wherein the core is formed from a polybutadiene blend comprising a) a first polybutadiene having a first Mooney viscosity between about 50 and about 150, and b) a second polybutadiene having a second Mooney viscosity between about 30 and about 100, wherein the first Mooney viscosity is greater than the second Mooney viscosity, and wherein the blend has a greater weight percentage of the first polybutadiene than that of the second polybutadiene.

Abstract: A golf ball comprising a core comprising a metal salt of an unsaturated organic acid and a halogenated organosulfur compound or a metal salt thereof, and a cover; wherein the metal salt of an unsaturated organic acid is present in an amount of less than about 20 pph and the halogenated organosulfur compound or a metal salt thereof is present in an amount of less than about 2 pph.

Abstract: A golf ball formed of a core and a cover, wherein the core has a diameter of at least about 1.50 inches and comprises a polybutadiene rubber composition comprising at least about 2.2 parts per hundred of a halogenated organosulfur compound, and wherein the cover has a thickness of less than about 0.1 inches and comprises a polyurethane composition.

Abstract: A golf ball comprising a core including a center having an outer diameter from about 0.375 inches to about 1.4 inches and deflection of greater than about 4.5 mm under a load of 100 Kg and an outer core layer having an outer diameter of from about 1.4 in to about 1.62 in, wherein at least one of the center or core layer includes polybutadiene rubber composition including a halogenated organosulfur compound or a metal salt thereof, and a cover including an inner cover layer having an outer diameter of greater than about 1.58 in and a material hardness of less than about 72 Shore D and an outer cover layer having a hardness of greater than about 50 Shore D and a material hardness of less than about 50 Shore D.
