摘要: The present invention provides a rubber composition having a high impact resilience, and improved processability and workability which may be used for the manufacture of a one-piece solid golf ball, the solid core of multi-layered solid golf balls or the solid centre of thread-wound golf balls. The rubber composition is characterized in that the rubber component is made from a mixture of:
(1) 60 to 95 wt% of a polybutadiene containing at least more than 40% of cis-1,4-bonds and having a Mooney viscosity [ML₁₊₄(100°C)] of 50 to 70, obtained by using a lanthanum rare earth-based catalyst, nickel-based catalyst or cobalt-based catalyst, or a mixture thereof with another polybutadiene obtained by using a catalyst other than the above mentioned one, and
(2) 5 to 40 wt% of a polyisoprene containing at least more than 90% of cis-1,4-bonds and a Mooney viscosity of 70 to 90.摘要翻译: 本发明提供了具有高冲击弹性和改进的加工性能和可加工性的橡胶组合物,其可用于制造单件固体高尔夫球,多层固体高尔夫球的实芯或固体中心线 - 高尔夫球。 橡胶组合物的特征在于,橡胶组分由以下混合物制成:(1)60至95重量%的含有至少大于40%的顺式-1,4-键并具有门尼粘度[ML1 +4(100℃)]为50〜70,通过使用稀土类稀土系催化剂,镍系催化剂或钴系催化剂,或其与使用除上述以外的催化剂而得到的其它聚丁二烯的混合物 和(2)5〜40重量%的含有至少大于90%的顺式-1,4-键和门尼粘度为70〜90的聚异戊二烯。
