    Abstract: Multi-piece golf balls containing a multi-layered core structure are provided. The core structure includes a small, heavy inner core (center) having a relatively high specific gravity, an intermediate core layer, and a surrounding outer core layer. The layers of the core structure may have different hardness gradients. The center of the core comprises a metal material such as copper, steel, brass, tungsten, titanium, aluminum, and alloys thereof dispersed in a thermoset polymeric matrix. The intermediate core layer is preferably formed from a first thermoplastic composition such as an ethylene acid copolymer ionomer resin; and the outer core layer is preferably formed from a second thermoplastic composition. The resulting ball has high resiliency and good spin control.

    Abstract: Multi-layered golf balls containing a two-layered core assembly are provided. Preferably, at least one of the core layers is formed from a thermoplastic composition that comprises: a) thermoplastic non-acid polymer, and b) plasticizer. In one preferred embodiment, the inner core is made of a first thermoplastic composition comprising the non-acid polymer and plasticizer; and the outer core layer is made of a second thermoplastic composition. For example, an ethylene acid copolymer may be used to form the outer core layer. A fatty acid ester such as ethyl oleate is preferably used as the plasticizer. Suitable non-acid polymers include, for example, polyesters, polyamides, polyolefins, and polyurethanes. The core assembly has a relatively high resiliency at given compressions.

    Abstract: Golf ball incorporating thermoplastic blend of (i) ionomer(s); (ii) different thermoplastic polymer(s) selected from thermoplastic polyurethane(s), thermoplastic urea(s), and/or thermoplastic urea-urethane hybrid(s); and (iii) polyester elastomer(s) and/or polyamide elastomer(s) (“PEPA”). Ionomer is present in amount of about 45 wt % or greater and PEPA present in amount of from about 2 wt % to about 35 wt %. Thermoplastic polymer(s) may be present in amount of from about 8 wt % to about 50 wt %; or from about 25 wt % to about 45 wt %; or from about 35 wt % to about 50 wt %. Ionomer amount may be greater than amount of thermoplastic polymer. Thermoplastic polymer may be a polyurethane present in amount of greater than 20 wt % and to about 40 wt %; while the PEPA is present in amount of from about 5 wt % to about 30 wt %. PEPA is sometimes present in an amount of from about 15 wt % to about 35 wt %.
