Abstract
The present invention provides a rubber composition for obtaining golf ball having excellent rebound characteristics and excellent durability, and showing good workability when producing. The present invention relates to a rubber composition for golf ball comprising a base rubber, a co-crosslinking agent, an organic peroxide and an inorganic filler, wherein the base rubber comprises a polybutadiene (a) containing a cis-1,4 bond of not less than 80%, having a Mooney viscosity of not less than 30 to less than 50 ML1+4 (100° C.) and a ratio (Mw/Mn) of weight average molecular weight (Mw) to number average molecular weight (Mn) of 3.0 to 6.0, synthesized using lanthanide-containing catalyst.
