Abstract
A golf ball, typically its core, is manufactured by molding and vulcanizing a rubber composition comprising a base rubber, an unsaturated carboxylic acid or a metal salt thereof, an inorganic filler, an organic peroxide, and an organosulfur compound. The base rubber contains a polybutadiene having a Mw of 60–150×10and a Mw/Mn of up to 2.0 and containing at least 98% of cis-1,4 bonds and up to 1.5% of trans-1,4 bonds. The composition is easy to mold and work, and the golf ball has good rebound and improved flight performance.
