    摘要： A low compression, resilient golf ball having a center and a cover, wherein at least a portion of the ball is formed from the conversion reaction of an amount of polybutadiene, a free radical source, and a cis-to-trans catalyst including at least one inorganic sulfide at a sufficient temperature to form a polybutadiene reaction product which includes an amount of trans-polybutadiene greater than the amount of trans-polybutadiene present before the conversion reaction and a cis-to-trans catalyst including at least one inorganic sulfide. The reaction product preferably 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, wherein at least a portion of at least one of the center, intermediate layer, or both, are made from the reaction product. Also included are methods of forming such golf balls.

    摘要： 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 aromatic component, and a free radical source. The reaction product typically 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 aromatic component and a free radical source. In particular, the use of various combinations of polybutadiene, cis-to-trans catalyst including at least one aromatic component, free radical source, filler, and crosslinker, produces golf balls and golf ball components that are resilient (fast) and have low compression (soft).
