Abstract: A golf ball includes a core and a cover layer. The core is formed of a first composition and the cover is formed of a second composition. The specific gravity values of each of the first and second compositions are generally equal to each other. The first and second compositions are each sufficiently mixed such that the ball exhibits random orientation when floated in a solution of sufficient density to support the ball. The weight, size, spherical symmetry, initial velocity and overall distance of the ball conform to the requirements of the United States Golf Association.

Abstract: A golf ball includes a core, an intermediate layer and a cover. The core is formed of a first composition, the intermediate layer is formed of a second composition, and the cover is formed of a third composition. The specific gravity of each of the first, second and third compositions are generally equal to each other. The first, second, and third compositions are each sufficiently mixed such that the ball exhibits random orientation when floated in a solution of sufficient density to support the ball.

Abstract: A golf ball includes a wound center and a cover made from fast curing polyurethane. The fast curing polyurethane is a two-component polyurethane which includes an isocyanate and a mixture of isocyanate reactive compounds comprising polyether or polyester polyol, aliphatic or aromatic (di) amines, and chain extenders, catalysts, internal mold release agent as needed.

Abstract: A golf ball includes a solid core which includes a blend of polybutadiene and polyurethane rubber. The rubber component of the core consists of 70 to 95% by weight of a high cis content polybutadiene rubber and 5 to 30% by weight of polyurethane rubber. The core also includes an acrylate of a zinc salt and an organic peroxide initiator.

Abstract: A golf ball includes a cover which includes a blend of polybutadiene and polyurethane rubber. The rubber component of the core consists of 10-90% by weight of polyurethane rubber and 10 to 60% by weight of a high cis content polybutadiene rubber. The cover also includes a crosslinking agent and a crosslinking initiator.

Abstract: Golf balls exhibiting an improved coefficient of restitution are obtained by including zinc palmeatate in the core formulation.
