ABSTRACT:
Homogeneous molded one and two-piece golf balls exhibiting, improved compression and fracture strength while maintaining desired rebound, click and feel required in a golf ball, are disclosed. The core of the golf ball is obtained by curing a composition comprising: (a) 100 parts by weight, of a polybutadiene elastomer containing at least 40% cis-1, 4-unsaturation; (b) from about 10 to about 50 parts, by weight, of a coagent comprising (i) an admixture or a reaction product of a polyvalent metal salt of an unsaturated carboxylic acid and an active hydrogen-containing organic filler or (ii) a reaction product obtained by the reaction of unsaturated carboxylic acid with an active hydrogen-containing organic filler, followed by further reaction with a polyvalent metal compound in the presence of said unsaturated carboxylic acid whereby said coagent functions as a crosslinking agent with the polybutadiene elastomer; (c) from about 10 to 30 parts, by weight, of an inert particulate mineral filler; and (d) from about 0.5 to 10 parts, by weight, of a polymerization initiator.
