A rubber composition for a solid golf ball contains a polybutadiene rubber component, a co-crosslinking agent, an organic peroxide, a filler, and an organic sulfur compound. When a core for a solid golf ball is formed by using the rubber composition for a solid golf ball, the content of a trans-structure in a cross-linked polybutadiene rubber component on the surface of the core is in a range of 20 to 39%, and a value obtained by subtracting the content of the trans-structure in the cross-linked polybutadiene rubber component at the center of the core from the content of the trans-structure in the cross-linked polybutadiene rubber component on the surface of the core is in a range of 5 to 35%. A solid golf ball produced by using such a core is excellent in hit feeling and flight characteristics. A method of producing a core for a solid golf ball makes it possible to simply produce the core specified as described above.
一种用于实心高尔夫球的橡胶组合物含有聚丁二烯橡胶成分、共交联剂、有机过氧化物、填料和有机硫化合物。当使用实心高尔夫球用橡胶组合物形成实心高尔夫球芯时,球芯表面交联聚丁二烯橡胶成分中的反式结构含量在 20% 至 39% 之间、从球芯表面的交联聚丁二烯橡胶成分中的反式结构含量减去球芯中心的交联聚丁二烯橡胶成分中的反式结构含量后得到的数值范围为 5%至 35%。使用这种球芯生产的实心高尔夫球具有极佳的击球感和飞行特性。生产实心高尔夫球芯的方法可以简单地生产出上述指定的球芯。
