Abstract:
A golf ball having a cover disposed about a core, wherein the golf ball comprises a material formed from the conversion reaction of a sufficient amount of polybutadiene, a free radical source, and a cis-to-trans catalyst comprising at least one organosulfur component, wherein the reaction occurs at a sufficient temperature to form a polybutadiene reaction product, wherein the golf ball comprises:at least about 32 percent trans-polybutadiene after the conversion reaction, wherein the amount of trans-polybutadiene after the conversion reaction is greater than the amount of trans-polybutadiene present before the conversion reaction; and a cis-to-trans catalyst comprising at least one organosulfur component, wherein the reaction product comprises a sphere which has a midpoint having a first hardness and a surface having a second hardness such that the second hardness differs from the first hardness by greater than 10 percent of the first hardness.
