    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 comprising a single layer core and a cover layer disposed about the single layer core, the 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, an outer core region adjacent the outer surface, and an intermediate core region disposed between the inner and outer core regions and extending radially from about 8 mm to about 18 mm from the geometric center. The single layer core has first, second and third hardness disposed within the inner core region, outer core region, intermediate core region, respectively, wherein the third hardness is greater than the first hardness and the second hardness, and a hardness of the outer surface is substantially the same as or lower than a hardness of the geometric center.

    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 wherein an inner core region is disposed about the geometric center and an outer core region is disposed about the inner core region and is adjacent the outer surface, the outer core region having a thickness of about 15 mm or less. The inner core region has a first hardness (IC1h) and the outer core region has a second hardness (OC2h) such that the second hardness (OC2h) is greater than the first hardness (IC1h), represented by the relationship (OC2h)>(IC1h) and a hardness of the outer surface (OSh) is greater than a hardness of the geometric center (GCh), represented by the relationship (OSh)>(GCh) to define a positive hardness gradient.

    摘要: Golf balls having a core comprising a polyalkenamer rubber composition are provided. The rubber composition may further include other rubbers such as, for example, polybutadiene, polyisoprene, ethylene propylene rubber, ethylene propylene diene rubber, and styrene-butadiene rubber. The rubber composition helps improve resiliency of the core and provides the ball with a comfortable and soft feel. In one version, a solid, single core having an outer surface and geometric center is provided, wherein the outer surface has a hardness greater than the hardness of the geometric center to define a positive hardness gradient of at least 10 Shore C. In a second version, a dual-core having an inner core and surrounding outer core layer is provided. The inner core has a positive hardness gradient, while the outer core has a zero; negative; or positive hardness gradient.
