Abstract:
Multi-layered golf balls containing a dual-core structure are provided. The core structure includes an inner core (center) comprising a foam composition, preferably foamed polyurethane. The outer core layer is preferably formed from a non-foamed thermoset composition such as polybutadiene rubber. The core layers have different hardness and specific gravity levels. The specific gravity (density) of the foam inner core is preferably less than the density of the outer core layer. The core assembly preferably has a positive hardness gradient extending across the entire assembly. The core structure and resulting ball have relatively good resiliency.

Claim (Index 1):
A core assembly for a golf ball, comprising:\n i) an inner core layer comprising a foamed composition, the inner core layer having a diameter in the range of about 0.100 to about 1.100 inches, a specific gravity (SG inner ), and an outer surface hardness (H inner core surface ) and a center hardness (H inner core center ), the H inner core surface  being the same or less than the H inner core center  to provide a zero or negative hardness gradient; and ii) an outer core layer comprising a thermoset material, the outer core layer being disposed about the intermediate core layer and having a thickness in the range of about 0.100 to about 0.750 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 outer , is greater than the SG inner , and the center hardness of the inner core (H inner core center ) is in the range of about 10 Shore C to about 60 Shore C and the outer surface hardness of the outer core layer (H outer surface of OC ) is in the range of about 65 Shore C to about 96 Shore C to provide a positive hardness gradient across the core assembly.
