    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.
