Abstract:
1. A golf ball having a cover and a core, wherein the core comprises a material formed from the conversion reaction of polybutadiene, a free radical source comprising a single peroxide, and a cis-to-trans catalyst comprising zinc pentachlorothiophenol, wherein the conversion reaction occurs at a sufficient temperature to form a polybutadiene reaction product comprising: a second amount of trans-isomer content greater than the first amount of trans-isomer content, wherein the material has a free radical source to antioxidant ratio of about 25 or greater, wherein the cis-to-trans catalyst is present in an amount of about 2.2 parts per hundred or greater, and wherein a first hardness measured at an interior location in the core differs from a second hardness measured at an exterior surface on the core by at least about 10 percent wherein the golf ball has a coefficient of restitution of about 0.81 or greater.
