Abstract:
A golf ball having a cover and a core said core being formed from a composition comprising a base elastomer selected from polybutadiene and mixtures of polybutadiene with other elastomers, said polybutadiene having a molecular weight of from about 50,000 to about 500,000, at least one metallic salt of an .alpha., .beta.-ethylenically unsaturated monocarboxylic acid, a free radical initiator, and from about 10 to about 100 parts by weight of a polypropylene powder resin based on 100 parts by weight elastomer, wherein said polypropylene powder resin enhances the hardness of the core thereby reducing the amounts of the metallic salt of an .alpha., .beta.-ethylenically unsaturated monocarboxylic acid incorporated with the core relative to cores free of polypropylene.
