    • 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, an outer core region is adjacent the outer surface, and an intermediate core region is disposed between the inner and outer core regions and extends from at least about 2 mm radially from the geometric center to at least about 2 mm from the outer surface. The inner core region has a first hardness (IC1h), the outer core region has a second hardness (OC2h), the intermediate core region has third and fourth hardnesses (IMC3h) and (IMC4h), respectively, such that the third hardness is less than the first and second hardnesses, represented by the relationships (IMC3h) (IC1h) and (IMC4h)>(OC2h), and 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.

    • The present invention is directed to an improved multi-layered core golf ball wherein each core layer comprises its own specific hardness gradient (positive, negative or a combination) in addition to an overall specific hardness gradient from one core layer to the next. In a first embodiment, the golf ball comprises a two layer core and a cover disposed about the two layer core. The two layer core comprises an inner core layer and an outer core layer disposed about the inner core layer. The inner core layer comprises a geometric center and a first outer surface. The inner core layer is formed from a substantially homogenous formulation, comprises a diameter of about 30 mm or lower, and has a plurality of hardnesses of from about 60 Shore C to about 85 Shore C. The geometric center comprises a first hardness and the first outer surface comprises a second hardness wherein the second hardness is greater than the first hardness to define a positive hardness gradient of from about 5 Shore C to about 20 Shore C. The outer core layer comprises an inner surface and a second outer surface. The outer core layer is formed from a substantially homogenous formulation, comprises a thickness of about 10 mm or lower, and has a plurality of hardnesses of from about 60 Shore C to about 95 Shore C. The inner surface comprises a third hardness and the second outer surface comprises a fourth hardness wherein the fourth hardness is greater than the third hardness to define a positive hardness gradient of about 20 Shore C or lower. The third hardness may be similar to the second hardness. The outer core layer further comprises a fifth hardness disposed between the inner surface and the second outer surface in a region extending between about 10% and about 90% of the distance from the inner surface to the second outer surface, wherein the fifth hardness is greater than the third hardness and the fourth hardness. Alternatively, the region may extend radially from about 13 mm to about 20 mm from the geometric center. Finally, the fourth hardness is greater than the first hardness to define a positive hardness gradient of about 30 Shore C or lower. In a second embodiment, the outer core layer differs from that of the first embodiment at least in that: the fourth hardness is less than the third hardness to define a negative hardness gradient of about 20 Shore C or lower; the fifth hardness is less than the third hardness and the fourth hardness; and the fourth hardness is greater than the first hardness to define a positive hardness gradient of about 18 Shore C or lower. The present invention is also directed to a golf ball having certain Shore D hardnesses as disclosed herein.

    • A golf ball comprising of an outer core layer, or an inner cover layer having heat resistant properties to facilitate compression molding of a thermosetting polybutadiene-comprising layer over at least one thermoplastic layer. The ball comprises a thermoplastic inner core or core layer comprising of a low vicat highly neutralized ionomer material having a low melting point of less than 100° C., and a Shore C surface hardness of less than 80 and a compression of less than 70, wherein an outer adjacent thermoset layer is placed around the inner core or core layer, the thermoset layer comprising comprising a peroxide that decomposes at low temperatures forming free radical initiators with short half lives, therein reducing the molding temperature of the high vicat layer and subsequently reducing the temperature and/or time the softer thermoplastic layer is exposed to the high heat.
