Abstract:
A method for decreasing the amount of a metallic salt of an unsaturated carboxylic acid and increasing the amount of a mineral filler in a core of a golf ball having core and a cover, said core being formed from a composition having a base elastomer selected from polybutadiene and mixtures of polybutadiene with other elastomers, at least one metallic salt of an unsaturated carboxylic acid, a free radical initiator and a mineral filler, said method comprising the steps of adding to the core composition from about 10 to about 100 parts by weight of a polypropylene powder resin based on 100 parts by weight of an elastomer, thereby reducing the amount of a metallic salt of the unsaturated monocarboxylic acid and increasing the amount of the mineral filler to be included in the golf ball core composition relative to cores free of polypropylene.
