    Abstract: A golf ball including a core and a cover including a thermoplastic inner cover layer having a material hardness of 60 to 80 Shore D; a thermoset outer cover layer comprising a castable polyurea and having a material hardness of 20 to 60 Shore D; and a thermoset intermediate cover layer disposed between the inner and outer cover layers and having a hardness substantially the same as the inner cover layer hardness and greater than the outer cover layer hardness. The inner cover includes one or more high- or low-acid ionomers and, optionally, a maleic anhydride modified polyolefin. The intermediate layer is formed from a castable liquid polybutadiene rubber.

    Abstract: Multi-layered golf balls containing a two or three-layered core assembly are provided. In one embodiment, the core assembly includes an inner core (center) comprising a thermoset composition, an intermediate core layer; and surrounding outer core layer. Preferably, the thermoplastic composition comprises: a) ethylene acid copolymer, b) plasticizer, and c) cation source. A fatty acid ester such as ethyl oleate is preferably used as the plasticizer. A second thermoset composition such as polybutadiene rubber may be used to form the outer core layer. The core layers have different hardness levels. In another embodiment, a two-layered core structure is provided. For example, the inner core and/or outer core layer may be made of the plasticized thermoplastic composition. The core structure and resulting ball have relatively good resiliency at given compressions.

    Abstract: Golf balls having cores with negative hardness gradients are provided. The cores are made of polyalkenamer rubber compositions that may further include other rubbers such as, for example, polybutadiene, polyisoprene, ethylene propylene rubber, ethylene propylene diene rubber, and styrene-butadiene rubber. In one version, a solid, single core having an outer surface and center is provided, wherein the outer surface has a hardness substantially the same or lower than the hardness of the center to define a zero or negative hardness gradient. Dual-cores having inner and outer cores can be made, wherein the inner core has a negative hardness gradient and the outer core has a positive or negative hardness gradient. The rubber composition helps improve resiliency of the core and provides the ball with a comfortable and soft feel.

    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.
