    Abstract: A golf ball comprising a single layer core formed from a substantially homogenous formulation and comprising a geometric center and an outer surface; a hardness of the outer surface is greater than a hardness of the geometric center. An inner core region is disposed about the geometric center and has a first hardness that is less than those of the geometric center and the outer surface; an outer core region is adjacent the outer surface and has a second hardness that is greater than those of the geometric center and the outer surface; and an intermediate core region is disposed between the inner and outer core regions and extends radially from about 5 mm to about 15.75 mm from the geometric center and has at least a third hardness and a fourth hardness, each of which are related to the first hardness and the second hardness in various ways.

    Abstract: Low compression multi-piece golf balls having a solid core comprising at least one layer made of a plasticized thermoplastic composition are provided. Preferably, the ball has a compression of less than 60 and more preferably less than 50. The ball includes a cover in addition to the core sub-assembly. For example, two-piece and three-piece golf balls may be made. The plasticized thermoplastic composition preferably comprises: a) ethylene acid copolymer, b) plasticizer, and c) cation source. Preferably, a fatty acid ester such as butyl oleate is used as the plasticizer. In two-layered core constructions, the outer core layer is preferably formed from a thermoset composition such as polybutadiene rubber. The core layers may have different hardness levels. The core structure and resulting ball have relatively good resiliency at given compressions.

    Abstract: Golf ball comprising a single layer core formed from a substantially homogenous formulation and comprising: geometric center and outer surface; inner core region disposed about the geometric center, outer core region adjacent the outer surface, and intermediate core region disposed between the inner and outer core regions and extending radially from about 10 mm to about 16 mm from the geometric center. A first hardness is disposed within the inner core region, a second hardness is disposed within the outer core region, and a third hardness of from about 40 Shore C to about 95 Shore C (or about 30 Shore D to about 70 Shore D) is disposed within the intermediate core region and is greater than each of the first and second hardnesses. At least one hardness in the outer core region is substantially the same as or less than a hardness in the inner core region.

    Abstract: Multi-layered golf balls having a dual-layered core and cover of at least one layer are provided. The dual-core construction includes a non-foamed inner core (center) made of a thermoplastic or thermoset composition such as polybutadiene rubber. An outer core layer comprising a foamed composition, such as polyurethane foam, is disposed about the inner core. In one version, the foamed outer core layer is made of a relatively soft foam composition having low flex modulus and density. The foamed outer core layer may specific gravity gradient within the layer, wherein the outer surface specific gravity is greater than the midpoint specific gravity. A cover may be disposed about the core structure. For example, an inner cover made of ethylene acid copolymer ionomer and outer cover made of polyurethane may be used.
