Abstract
A low compression, resilient golf ball having a center and a cover, made from a polybutadiene reaction product having polybutadiene, a cis-to-trans catalyst including an organosulfur component, and a free radical source. The reaction product has a first dynamic stiffness measured at −50° C. that is less than about 130 percent of a second dynamic stiffness measured at 0° C. A multi-layer golf ball having a center, at least one intermediate layer disposed concentrically about the center, and a cover. At least a portion of at least one of the center, intermediate layer, or both, are made from a reaction product including polybutadiene having a cis-to-trans catalyst that includes at least one organosulfur component and a free radical source. The reaction product has a first dynamic stiffness measured at −50° C. that is less than about 130 percent of a second dynamic stiffness measured at 0° C. Addition of various combinations of polybutadiene, cis-to-trans catalyst including at least one organosulfur component, free radical source, filler, and crosslinker, produce golf balls and golf ball components that are resilient (fast) and have low compression (soft).
