Abstract
The golf ball has a solid core and a cover surrounding the core. The solid core is formed of a rubber composition that has a co-crosslinking agent and preferably an organic sulfur compound blended therein, with a portion of the co-crosslinking agent and the organic sulfur compound being micro-encapsulated within a thermoplastic resin, and a remaining portion of the co-crosslinking agent being in a non-encapsulated state. This improves dispersibility of the co-crosslinking agent and the organic sulfur compound within the rubber composition, and enables adjustment of the crosslinking pattern of the rubber molecule main chains. Thus, resilience and durability of the golf ball are improved.
Claims6
A method of manufacturing a golf ball having a solid core and a cover surrounding the solid core, comprising the steps of:
- blending a co-crosslinking agent into a rubber composition, with a portion of the co-crosslinking agent being micro-encapsulated within a thermoplastic resin;
- and
- heating said rubber composition at a temperature higher than a softening point of said thermoplastic resin for crosslinking.
