Abstract
A golf ball which is formed from a crosslinked rubber compound composed of, as essential components, (A) a rubber base material composed of (a) a polybutadiene containing no less than 60 wt % of cis-1,4 bonds and having a Mooney viscosity (ML(100° C.)) of 50 to 120, which is synthesized by using a group VIII catalyst element and/or a rare earth element-based catalyst, and (b) a solid isoprene rubber containing no less than 60 wt % of cis-1,4 bonds and having a Mooney viscosity (ML(100° C.)) of 70 to 90, with the ratio of (a) to (b) being from 96/4 to 99/1 by weight; (B) an unsaturated carboxylic acid and/or a metal salt thereof; and (C) an organic peroxide. The golf ball is characterized by good rebound resilience and good workability with which it is produced.
