Abstract
One-piece golf balls or golf ball cores are obtained by molding and vulcanizing a rubber composition which includes (A) a polybutadiene-containing base rubber and (B) methacrylic acid. By including in the rubber composition (C) from 0.1 to 0.5 part by weight of a maleimide per 100 parts by weight of component A, the vulcanization time during molding and vulcanization is shortened, which enhances productivity without altering the performance and properties of the molded and vulcanized material.
Claims9
A rubber composition for golf balls, comprising:
- (A) a polybutadiene-containing base rubber;
- (B) methacrylic acid;
- and
- (C) a maleimide,
- wherein component C is included in an amount of from 0.1 to 0.5 part by weight per 100 parts by weight of component A.
A method of manufacturing golf balls, comprising the step of molding and vulcanizing, for a vulcanization time, a rubber composition which includes (A) a polybutadiene-containing base rubber and (B) methacrylic acid so as to obtain a golf ball core or a one-piece golf ball, wherein the vulcanization time during molding and vulcanization is shortened by including in the rubber composition (C) from 0.1 to 0.5 part by weight of a maleimide per 100 parts by weight of component A.
