Abstract: Solid golf balls are produced by the method comprising the steps of preparing a polymer cement in a suitable organic solvent, forming a suspension of the metal salt of an alpha , beta -ethylenically unsaturated carboxylic acid in a suitable aliphatic hydrocarbon solvent miscible with the organic solvent, mixing the polymer cement and the suspension together, removing the solvents to provide the metal salt uniformly dispersed within the polymer. and thereafter manufacturing a solid golf ball therefrom. Solid golf balls comprise a vulcunizable rubber and from about 5 to 100 parts by weight of a reinforcing filler comprising a metal salt of an alpha , beta -ethylenically unsaturated carboxylic acid, per 100 parts of the vulcanizable rubber. When the metal salts are incorporated via solution masterbatching, the resulting golf balls have improved physical properties.

Abstract: One-piece and multi-layered golf balls are improved in flight performance by forming the one-piece ball entirely or multi-layered golf ball core from a rubber composition comprising a base rubber and a co-crosslinking agent in the form of a premix of an unsaturated fatty acid metal salt and a liquid polymer such as liquid polybutadiene.

Abstract: Solid golf balls comprise a vulcanizable rubber and a reinforcing filler comprising an essentially anhydrous metal salt of an alpha , beta -ethylenically unsaturated carboxylic acid. Golf balls containing such reinforcing fillers have improved physical properties over rubber compounds containing conventional metal carboxylic acid salts. Additionally, the rubber compounds have improved processability and shorter curing time.

Abstract: In a thread-wound golf ball comprising a thread-wound core and a cover, the cover is formed of a vulcanized rubber composition comprising a base rubber containing at least 30% by weight of transpolyisoprene and has a vulcanizing sulfur content ratio between radially outer and inner half regions of from 1/2 to 4/1. Sufficient vulcanizing sulfur available throughout the cover renders the cover to be resistant to cut and shear so that the ball becomes durable.
