    摘要: A low compression, resilient golf ball having a center including a material formed from the conversion reaction of sufficient amounts of polybutadiene, a free radical source, and a cis-to-trans catalyst to convert a portion of cis-isomer to trans-isomer in the polybutadiene, which reaction occurs at a sufficient temperature to form the material that contains trans-isomer and cis-isomer, wherein said material has an amount of trans-isomer greater than the amount of trans-isomer present before the conversion reaction, at least one intermediate layer disposed about the center and including a resilient polymer component and a reinforcing polymer component present in an amount sufficient to provide an uncrosslinked first mixture having a rigidity as determined by a flexural modulus greater than about 3.5 MPa, wherein the center and each intermediate layer together form the core, and a cover being disposed about the core, wherein the golf ball has a diameter of at least about 1.68 inches. In particular, the cis-to-trans catalyst includes an organosulfur compound, a Group VIA component, an inorganic sulfide, or a combination thereof, and the reinforcing polymer includes trans-polyisoprene. The invention also relates to golf balls formed from a conversion between various combinations of polybutadiene, cis-to-trans catalyst, free radical source, and optional filler and/or crosslinking agent, to produce a desired golf ball or golf ball component, such as those that are resilient (fast) and have low compression (soft).
