    摘要： Golf balls having a hard outer skin produced from a material that includes crosslinks in both the hard and soft segments of the polymer backbone that improve the crosslink density. Compositions formed from polyurethane and/or polyurea prepolymers that are first cured with a curative blend including an isocyanate-reactive component to crosslink the hard segment and then exposed to a free radical initiator and radiation to crosslink the soft segments are used in an outer layer of a golf ball, a unitary golf ball, or other golf ball constructions.

    摘要： A golf ball comprising a single layer core and a cover layer disposed about the single layer core, the single layer core being formed from a substantially homogenous formulation and comprising a geometric center and an outer surface, the single layer core further comprising an inner core region disposed about the geometric center and having a thickness of about 5 mm or lower, an outer core region adjacent the outer core surface and having a thickness of about 5 mm or lower, and an intermediate core region disposed between the inner and outer core regions. The single layer core has a first hardness disposed within the inner core region, a second hardness disposed within the outer core region, and a third hardness disposed within the intermediate core region, wherein the first hardness and second hardness are greater than the third hardness and a hardness of the outer surface is substantially the same as or lower than a hardness of the geometric center.

    摘要： The present invention is directed to a golf ball having at least one layer formed from a rubber composition comprising a base rubber, a free radical initiator, and a quinhydrone. The free radical initiator is generally present in the rubber composition in an amount of at least 0.05 parts by weight per 100 parts of the base rubber. The quinhydrone is generally present in the rubber composition in an amount of at least 0.05 parts by weight per 100 parts of the base rubber. The rubber composition may be present in any one or more of a core layer, a cover layer, or an intermediate layer.

    摘要： Golf balls comprising a core and a cover are disclosed. The core is a dual- or multi-layer core, wherein at least one layer is formed from a rubber composition comprising a base rubber, a free radical initiator, and a hydroquinone. A ratio of the amount of the hydroquinone present in the rubber composition, measured in parts by weight, to the amount of free radical initiator present in the rubber composition, measured in parts by weight, is generally from 0.05 to 2. The core layer formed from such rubber composition has a positive hardness gradient such that the difference between the layer's outer surface hardness and inner surface hardness is 5 Shore C units or greater.

    摘要： A golf ball including an inner core having a first outer surface and a geometric center is formed from a substantially homogenous formulation such that the inner core generally has a hardness of 35 Shore C to 85 Shore C. An outer core layer is formed around the inner core and has a second outer surface and an inner surface, also 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 greater than the hardness of the geometric center to define a “positive hardness gradient,” and the hardness of the second outer surface is substantially the same as or lower than the hardness of the inner surface to define a “negative hardness gradient.”
