Abstract: A perimeter weighted golf ball with a low compression core is provided. The core preferably comprises a diene polymer that has low cross-link density or not cross-linked with a reactive co-agent. This core has low compression and low specific gravity. The low specific gravity core is encased within a thin dense layer positioned outside of the centroid radius to provide the ball with a high moment of inertia. The same core can be encased within a plurality of intermediate layers having either increasing hardness or decreasing hardness to provide selective golf balls for either low swing speed players or advanced players. Alternatively, a thin layer of diene polymer highly cross-linked with reactive a co-agent may be incorporated into the ball to increase the hardness of the ball.

Abstract: A golf ball having at least a core and a cover, wherein at least a portion of the ball is formed from a material resulting from the isomerization of an amount of polybutadiene in solution to create a resulting polybutadiene having an increased content of trans-polybutadiene, is disclosed. Isomerization can be accomplished by mixing a photo-sensitizer into the polybutadiene solution and exposing the resulting mixture to a radiation source such as ultraviolet radiation. Isomerization can also be accomplished thermally by mixing nitrogen dioxide into a sufficiently heated solution of polybutadiene and maintaining the mixture at an elevated temperature for a sufficient period of time to increase the trans-polybutadiene content of the polymer. The resulting polybutadiene is recovered, mixed with other additives as desired and formed into one or more portions of a golf ball.
