    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 having 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; 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 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： 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.
