Solid golf ball |
摘要 |
The present invention provides a solid golf ball containing the ultra-high molecular weight polybutadiene which is formulated therein in a solution form. The golf ball has very improved impact resilience and durability. The present invention provides a solid golf ball having at least a resilient portion therein formed from a rubber composition which comprises a base rubber, a crosslinking agent and a co-crosslinking agent, wherein said base rubber comprises a solid polybutadiene prepared by mixing the following components in solution form (a) 5 to 50% by weight of an ultra-high molecular weight polybutadiene rubber which has a cis-1,4-bond of at least 80% and a number average molecular weight of 40x104 or more, and (b) 95 to 50% by weight of a polybutadiene rubber which has a cis-1,4-bond of at least 80% and a number average molecular weight of less than 40x104.
