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 vulcanizable 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.
