    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: The present invention generally relates to golf balls and more particularly to golf balls having multi-layered cores comprising a thermoset rubber center, a thermoplastic intermediate core layer, and a thermoset rubber outer core layer. A cover layer is disposed about the multi-layered core. At least one of the center, intermediate core layer, and outer core layer comprises a polyalkenamer rubber. In one preferred embodiment, the center, intermediate core, and outer core layers have positive hardness gradients. The core layers preferably have different specific gravities. The polyalkenamer rubber may be blended with other rubbers such as polybutadiene, polyisoprene, ethylene propylene diene, and styrene-butadiene rubbers. The polyalkenamer 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.
