<p>PURPOSE:To provide a solid golf ball excellent in a drive resisting property, ball driving feeling and productivity by composing the base material rubber of a mixture of specified solidified polybutadien rubber, liquefied polybutadien rubber and/or liquefied isoprene-butadien copolymer rubber. CONSTITUTION:A solid golf ball has at least a part of an elastic section formed of a rubber composition including base material rubber, cobridging agent and organic peroxide. The base material rubber is formed of a mixture of solidified polybutadien rubber having at least 40% of (A) cis-1.4-bond, (B) liquefied polybutadien rubber and/or liquefied isoprene butadien copolymer rubber and the mixing wt. ratio is preferably within the range of polybutadien rubber(A)/ liquefied rubber(B)= 98/2-72/25. For the cobridging agent is usually used 15-60wt. parts of unsaturated carboxilic acid and/or the metallic salt to 100wt parts of the base material rubber.</p> |
