摘要： PROBLEM TO BE SOLVED: To achieve a single layer core that has a soft-to-hard gradient from the surface to the center in a golf ball, and to achieve a method of producing such a core efficiently and at a low cost. SOLUTION: The golf ball has an inner core having a first outer surface and a geometric center and being formed from a substantially homogenous formulation such that the inner core has a hardness of 45 Shore C to 65 Shore C, and an outer core layer disposed about the inner core, having a second outer surface and an inner surface and being formed from a substantially homogenous formulation such that the outer core layer has a hardness of 55 Shore C to 90 Shore C. A cover layer is disposed about the outer core layer. The hardness of the first outer surface is the same as or 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".

摘要： The invention includes methods of forming at least a portion of a golf ball core, and the golf balls prepared thereby, by mixing a resilient polymer component, a free radical initiator system, and a crosslinking agent to provide a first mixture, forming the first mixture into a plurality of shells having a desired shape, first heat curing the shells at a temperature to impart a rigidity sufficient to maintain the desired shape until the shells are assembled and subsequently heat cured, quenching the first heat curing by reducing the shell temperature to inhibit crosslinking while a sufficient amount of free radical initiator system is present to facilitate a second heat curing, providing a center, assembling at least two shells concentrically about the center to form a first mantle layer, wherein the first mantle layer and center together form the ball core, and second heat curing the core at a temperature and for a time sufficient to further crosslink the first mixture and to at least partially crosslink the shells, thereby forming a cured golf ball core.

摘要： The present invention is directed to a golf ball containing a cover layer and a core layer, where the core layer is molded from a scorch retarding composition comprising a scorch retarding peroxide, an elastomeric polymer and a cross-linking agent. Preferably, the scorch retarding peroxide is present in an amount sufficient to delay cross-linking of the elastomeric polymer during core layer formation for a time sufficient to substantially prevent backrinding on the molded core layer. The golf balls of the invention may further comprise at least one intermediate layer interposed between the cover layer and the core layer, at least one of the layers being molded from a scorch retarding composition comprising a scorch retarding peroxide, an elastomeric polymer and a cross-linking agent. A method of making such golf balls is also disclosed.

摘要： A dual core golf ball and methods for preparing portions thereof including a core having at least one core layer, a mantle having at least one layer including an amount of reinforcing polymer component and a resilient polymer component disposed concentrically adjacent the core, and a cover layer disposed concentrically adjacent the mantle, wherein the at least one mantle layer is sufficiently rigid to inhibit the resilient polymer component from substantially altering shape prior to crosslinking. The invention also includes an elastomeric composition for the mantle that includes a resilient polymer component having a predominantly 1,4-cis content, a free-radical initiator, and a reinforcing polymer component having a sufficiently low viscosity at a mixing temperature to permit substantially uniform dispersion of the polymer component with the resilient polymer component and having a crystalline melting point sufficiently low to permit mixing while avoiding substantial crosslinking.
