Abstract:
Multi-piece golf balls containing a dual-layered core structure are provided. The core structure includes a small, heavy inner core (center) having a relatively high specific gravity, 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 outer core layer is preferably formed from a thermoplastic composition such as an ethylene acid copolymer ionomer resin. The resulting ball has high resiliency and good spin.

Claim (Index 1):
A golf ball having a multi-layered core, comprising:\n i) an inner core comprising a metal material dispersed in a thermoset polymeric matrix, the inner core having a diameter in the range of about 0.100 to about 1.100 inches, a specific gravity (SG inner ) of 1.60 to 6.25 g/cc, and an outer surface hardness (H center surface ) and a center hardness (H center material ), the H center surface  being the same or less than the H center material  to provide a zero or negative hardness gradient; ii) an outer core layer comprising a thermoplastic material, the outer core layer being disposed about the inner core and having a thickness in the range of about 0.200 to about 1.200 inches, a specific gravity (SG outer ), and an outer surface hardness ((H outer surface of OC ) and an inner surface hardness (H inner surface of OC ), the H outer surface of OC  being greater than the H inner surface of OC  to provide a positive hardness gradient, wherein the SG inner  is greater than the SG outer , and the diameter of the inner core layer is less than the thickness of the outer core layer; and iii) a cover having at least one layer disposed about the multi-layered core.
