Abstract:
Multi-piece 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 inner and outer core layers can have different hardness gradients. Preferably, the specific gravity (density) of the foam inner core is less than the density of the outer core layer. The ball further includes a cover of at least one layer and may include at least one casing layer. The core structure and resulting ball have relatively good resiliency.

Claim (Index 5):
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 inner core 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 the same or less than the H inner surface of OC  to provide a zero or negative hardness gradient, wherein the SG outer , is greater than the SG inner .
