Abstract: Multi-piece golf balls containing a dual-layered core and dual-layered cover are provided. The core structure includes a small, heavy inner core (center) having a relatively high specific gravity, and a surrounding outer core layer. The core layers may have different hardness gradients. The center of the core comprises a metal material such as copper, steel, brass, tungsten, titanium, aluminum, and combinations and alloys thereof preferably dispersed in a thermoplastic polymeric matrix. The outer core layer is preferably formed from a thermoset composition such as polybutadiene. The multi-layered cores and covers have selective specific gravity relationships between the different layers. This helps provide the ball with good flight distance and spin control. The resulting balls have good resiliency and other playing performance properties.

Abstract: Multi-piece golf balls containing a dual-layered core are provided. The ball further includes single or multi-layered covers. The core structure includes a small, heavy inner core (center) having a relatively high specific gravity, and a surrounding outer core layer. The core layers may have different hardness gradients. The center of the core comprises a metal material such as copper, steel, brass, tungsten, titanium, aluminum, and combinations and alloys thereof preferably dispersed in a thermoplastic polymeric matrix. The outer core layer is preferably formed from a thermoset composition such as polybutadiene. These multi-layered core constructions with metal-containing centers have selective specific gravity relationships between the different layers. This helps provide the ball with good flight distance and spin control. The resulting balls have good resiliency and other playing performance properties.

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: A golf ball comprising a layer formed from at least one of a thermoset material or a thermoplastic material throughout; the layer having a treated region and an untreated region; the treated region extending inward from an outer surface of the layer and comprising a UV resistance composition; and the untreated region not comprising the UV resistance composition. For example, the treated region may be infused with the UV resistance composition. The layer may be a cover or even an inner golf ball layer, which can sometimes become exposed during play. The UV resistance composition may be formed from a mixture of an ultraviolet light absorber (UVA) and a solvent, the UVA being selected from benzotriazole type stabilizers, hindered amine type stabilizers, phenolic type stabilizers, triazines, or combinations thereof, and the solvent comprising at least one of acetone, methyl ethyl ketone, methyl isobutyl ketone, ethyl acetate, or butyl acetate.

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.
