    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).

    摘要： Golf balls having a core including a material formed from a controlled-isomer polybutadiene, a crosslinking agent, and a free-radical initiator, or a reaction product thereof, and a cover having a plurality of dimples disposed about the core, wherein the controlled-isomer polybutadiene includes at least about 10 percent to 80 percent trans-isomer and no more than about 5 percent vinyl-configuration polybutadiene and wherein the controlled-isomer polybutadiene has both an absolute molecular weight of at least about 250,000 and a polydispersity of no more than about 3 prior to crosslinking. In particular, golf balls having a compression below about 80 without significant loss of resilience can be advantageously prepared with such materials. Methods of preparing such golf balls are also recited.

    摘要： A golf ball includes an inner core having an outer surface and a geometric center and being formed from a first substantially homogenous composition such that the inner core has a hardness of 45 Shore C to 65 Shore C. An intermediate layer is disposed about the inner core and has an outer surface and an inner surface and is formed from a thermoplastic composition comprising an ionomer whose acid groups are 100% neutralized such that the intermediate layer has a hardness of 20 Shore D to 80 Shore D. A cover layer is disposed about the outer core layer. The inner core outer surface hardness is lower than the hardness of the geometric center to define a negative hardness gradient, and the hardness of the outer surface of the intermediate layer is the same as the hardness of the inner surface to define a zero hardness gradient.

    摘要： A golf ball includes an inner core having a first outer surface and a geometric center and is formed from a first substantially homogenous formulation throughout such that the inner core has a hardness of 30 Shore C to 45 Shore C. An outer core layer is formed around the inner core and has a second outer surface and an inner surface and is formed from a second substantially homogenous formulation throughout such that the outer core layer has a hardness of 60 Shore C to 95 Shore C. A cover layer is formed around the outer core layer. The hardness of the first outer surface is lower than the hardness of the geometric center to define a negative hardness gradient, and the hardness of the second outer surface is greater than the hardness of the inner surface to define a positive hardness gradient.
