| 简介 |
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 (ML1+4 (100° C.)) of 50 to 120, which is synthesized by using a group VIII element catalyst 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 (ML1+4 (100° C.)) of 70 to 90, with the ratio of (a) to (b) being from 70/30 to 98/2 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. |
