    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 polyurethane composition are provided. The ball includes a dual-layered core having a foam inner core (center) and surrounding outer core layer. The outer core layer may be made from a non-foamed thermoset material such as polybutadiene rubber. The ball further includes an inner cover, preferably made from a thermoplastic ionomer. The outer cover may be made from a non-foamed thermoset or thermoplastic material such as polyurethane. The core and inner cover layers preferably have different densities so the Moment of Inertia of the ball is adjusted. Preferably, the specific gravity of the inner cover is greater than the specific gravity of the outer core, which is greater than the specific gravity of the inner core. The finished ball has good distance and low-spin properties.

    Abstract: A golf ball comprising a single layer core formed from a substantially homogenous formulation and comprising a geometric center and an outer surface; a hardness of the outer surface is greater than a hardness of the geometric center. An inner core region is disposed about the geometric center and has a first hardness that is less than those of the geometric center and the outer surface; an outer core region is adjacent the outer surface and has a second hardness that is greater than those of the geometric center and the outer surface; and an intermediate core region is disposed between the inner and outer core regions and extends radially from about 5 mm to about 15.75 mm from the geometric center and has at least a third hardness and a fourth hardness, each of which are related to the first hardness and the second hardness in various ways.
