    摘要: The present invention is directed towards a method of forming a multilayer golf ball which comprises a core, an inner cover layer and an outer cover layer. The steps include forming a golf ball core; molding an inner cover layer around said golf ball core with a material having a first shore D hardness; and casting an outer cover layer around said inner cover layer and golf ball core with a thermoset material having a second shore D hardness less than the first. The core is comprised of a center made from a first rubber based material and an outer layer formed from a second rubber based material. Preferably, the first rubber based material has about 15 to 25 parts of a crosslinking agent per hundred parts of rubber and the second rubber based material has about 20 to 40 parts of a crosslinking agent per hundred parts of rubber.

    摘要: A golf ball includes a core formed of an inner core and at least one outer core layer disposed about the inner core, one of which includes a surface amount of trans-polybutadiene and an interior amount of trans-polybutadiene at least 6 percent less than the surface amount. A cover containing an inner cover layer and an outer cover layer is formed over the core. The inner cover layer includes a block copolymer of styrene and butadiene, isoprene, or ethylene-butylene rubber and has a material hardness of about 60 to 70 Shore D. The outer cover layer is formed from a castable polyurethane or polyurea and having a material hardness of 55 Shore D or less. The inner core has an interior hardness and a surface hardness differing from the interior hardness by greater than 20 percent.
