Abstract
A golf ball center composition comprising by weight 100 parts of a resilient elastomer, not more than 25 parts of a monomer capable of grafting, cross-linking or chain-extending the elastomer and not less then 70 parts of an inert filler, the composition being cured and having a Shore C hardness of not less than 60.degree.; a golf ball comprising said center, an elastic thread wound around the center to form a core, and a cover molded onto the core; and a method of making such golf ball.
Claims19
A golf ball comprising a center, an elastic thread wound around the center to form a core, and a cover molded onto the core, the center being formed from a composition comprising:
- (1) a cis-polybutadiene elastomer having a cis-content of not less than 80%;
- (2) not more than 25 parts by weight per hundred parts of elastomer of a monomer capable of grafting, cross-linking or chain extending the elastomer said monomer is selected from the metal salt of an unsaturated carboxylic acid and a polyol ester or anhydride of a polybasic unsaturated carboxylic acid;
- and
- (3) not less than 135 parts by weight per hundred parts of elastomer of an inert filler;
- said composition being cured and having a Shore C hardness of not less than 60.degree. and being characterized by not requiring freezing of the center in order to wind the elastic thread around the center.
A golf ball center composition comprising by weight 100 parts of a cis-polybutadiene elastomer having a cis-content of not less than 80%, not more than 25 parts of a monomer capable of grafting, cross-linking or chain-extending the elastomer said monomer is selected from the metal salt of an unsaturated carboxylic acid and a polyol ester or anhydride of a polybasic unsaturated carboxylic acid and not less than 135 parts of an inert filler, the composition being cured and having a Shore hardness of not less than 60.degree. and being characterized by not requiring freezing in order to wind an elastomeric thread around the center to form a golf ball core.
A golf ball center composition comprising by weight 100 parts of a cis-polybutadiene elastomer having a cis-content of not less that 80%, not more than 25 parts of a monomer which is a metal salt of an unsaturated carboxylic acid and which is capable of grafting, cross-linking or chain-extending the elastomer and not less than 135 parts of an inert filler, the composition being cured and having a Shore C hardness of not less than 60.degree. and being characterized by not requiring freezing in order to wind an elastomer thread around the center to form a golf ball core.
