    Abstract: A golf ball includes an inner core layer including a thermoplastic highly-neutralized ionomer formed from a copolymer of ethylene and an α,β-unsaturated carboxylic acid, an organic acid or salt thereof, and sufficient cation source to neutralize the acid groups of the copolymer by 80% or greater. The inner core has a geometric center hardness and a surface hardness to define a first hardness gradient. An outer core layer is disposed about the inner core and is formed from a homogenous thermoset composition. The outer core layer has an interior hardness and an outer surface hardness to define a second hardness gradient. An inner cover layer is disposed about outer core layer and an outer cover layer is disposed about the inner cover layer. A slope of the second hardness gradient is greater than a slope of the first hardness gradient.

    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: Golf ball comprising a core comprising: an untreated region extending radially from a geometric center a distance DUTr, a treated region disposed about the untreated region and extending inward from an outer surface a depth DTr; and an intermediate untreated region disposed about the untreated region and adjacent the treated region. The treated region is exposed to and comprises a fatty acid and/or fatty acid salt composition, and has a first hardness. The untreated region and intermediate untreated region have second and third hardnesses, respectively, and have not been exposed to and do not comprise the fatty acid and/or fatty acid salt composition. The first hardness is different than the second hardness and the third hardness. A first core layer comprises the untreated region, a second core layer, disposed thereabout, comprises the intermediate untreated region, and a third core layer, disposed about the second core layer comprises the treated region.

    Abstract: Multi-layered golf balls containing a two or three-layered cover assembly are provided. In one embodiment, the cover assembly includes a relatively hard inner cover and relatively soft outer cover. Alternatively, the cover assembly may include a relatively soft inner cover with a relatively hard outer cover. Three-layered covers comprising an inner cover, intermediate cover, and outer cover layer also may be prepared. Preferably, at least one of the layers is formed from a thermoplastic composition that preferably comprises: a) ethylene acid copolymer, b) plasticizer, and c) cation source. A fatty acid ester such as ethyl oleate is preferably used as the plasticizer. The cover assembly has good impact durability and helps provide the ball with relatively high resiliency at given compressions.
