Abstract: Multi-layered golf ball core sub-assemblies and the resulting golf balls are provided. The core structure includes an inner core (center) comprising a foam composition, preferably foamed polyurethane. The intermediate and outer core layers are preferably formed from foamed and non-foamed thermoset compositions. For example, the intermediate core can be formed from a thermoset rubber so there are adjoining foam core layers (inner and intermediate) and the outer core layer can be formed from a non-foamed thermoset rubber. The core layers have different hardness and specific gravity levels. The core assembly preferably has a positive hardness gradient extending across the entire assembly. The core structure and resulting ball have relatively good resiliency.

Abstract: The present invention generally relates to golf balls and more particularly to golf balls having multi-layered cores comprising a thermoset rubber center, a thermoplastic intermediate core layer, and a thermoset rubber outer core layer. A cover layer is disposed about the multi-layered core. At least one of the center, intermediate core layer, and outer core layer comprises a polyalkenamer rubber. In one preferred embodiment, the center, intermediate core, and outer core layers have positive hardness gradients. The core layers preferably have different specific gravities. The polyalkenamer rubber may be blended with other rubbers such as polybutadiene, polyisoprene, ethylene propylene diene, and styrene-butadiene rubbers. The polyalkenamer rubber composition helps improve resiliency of the core and provides the ball with a comfortable and soft feel.

Abstract: Multi-layered, golf balls having a core made of a foamed composition are provided. The core preferably has a foam inner core (center) and surrounding thermoset or thermoplastic outer core layer. The core also includes a structural insert such as, for example, a solid shell, perforated shell, a lattice or mesh, or a central hub with extending arms, and the like. The core layers have different hardness gradients and specific gravity values. The ball further includes a cover having at least one layer. By adjusting the respective specific gravity values of the core layers, the Moment of Inertia (MOI) of the ball can be increased or decreased. In one embodiment, the ball has generally good flight distance and low spin rate.
