Abstract: Golf balls having at least one layer comprising a polymer composition comprising a reaction mixture of a base polymer and at least one regenerating-type multi-functional antioxidant. A regenerating-type multi-functional antioxidant has at least two differing moieties selected for example from the group consisting of phenols, phosphites, amines or combinations thereof, and is macromolecular, having a molecular weight of at least 2,000 g/mol. and up to 2,000,000. The at least one layer may comprise at least one regenerating-type multi-functional antioxidant in an amount of from 0.10 to about 2.5 parts by weight per 100 parts by weight of the base polymer, or of less than 0.50 parts by weight per 100 parts by weight of the base polymer, or of less than 0.095 parts by weight per 100 parts by weight of the base polymer.

Abstract: Disclosed herein are polyurethane golf ball compositions. The compositions are prepared by adding a UV absorber to a polyol prior to reacting the polyol with an isocyanate to form a prepolymer, which is then reacted with a curing agent to form the polyurethane.

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.

Abstract: Multi-layered golf balls having a core, intermediate layer, and cover are provided. The ball includes a non-foamed inner core (center) made of a thermoplastic or thermoset composition such as polybutadiene rubber. An intermediate layer comprising a foamed composition, such as polyurethane foam, is disposed about the inner core. The foamed intermediate layer may have a specific gravity gradient within the layer, wherein the outer surface specific gravity is greater than the midpoint specific gravity. Ball constructions having two intermediate layers, wherein at least one layer is a foamed layer can be made. A cover having at least one layer is disposed about the intermediate layer.

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 including a thermoplastic inner core layer that has a geometric center hardness greater than its surface hardness to define a negative hardness gradient. An outer core layer is disposed about the inner core and is formed from a thermoplastic material and has an inner surface hardness substantially less than its outer surface hardness to define a positive hardness gradient. An inner cover layer is disposed about the outer core layer and an outer cover layer is disposed about the inner cover layer.

Abstract: Golf ball and method for making it, comprising a first layer that comprises a first polymeric composition and is surrounded by and adjacent to a second layer comprising a second polymeric composition different than the first polymeric composition; with one of these layers further comprising at least one silane-containing adhesion promoter such as organosilanes and/or organosiloxanes throughout in an amount of from about 0.1 wt. % to about 5.0 wt. % of the entire layer. Neither layer is surface treated with at least one silane-containing adhesion promoter. The second layer may be the layer comprising the silane-containing adhesion promoter throughout, surrounded by a third layer that comprises a third polymeric composition that differs from the second polymeric composition and does not incorporate any silane-containing adhesion promoter. Strong interlayer bonding is therefore created both between the second layer and the first layer and between the second layer and the third layer.

Abstract: A golf ball comprising an inner core layer including a thermoplastic material and having a geometric center hardness less than the surface hardness to define a positive hardness gradient. An outer core layer is formed over the inner core. The outer core includes a thermoset rubber composition and has an inner surface hardness less than an outer surface hardness to define a positive hardness gradient. A cover layer is formed over the outer core layer. The cover layer includes an inner cover layer and an outer cover layer. The thermoplastic material of the core includes an acid copolymer of ethylene and an α,β-unsaturated carboxylic acid, optionally a softening monomer comprising alkyl acrylate or methacrylate; a plasticizer; an organic acid or salt thereof; and a cation source present in an amount sufficient to neutralize from about 70 to about 100% of all acid groups present in the material.

Abstract: A golf ball includes an inner core layer having a first surface hardness and a geometric center hardness. The center hardness is less than the first surface hardness to define a first positive hardness gradient of about 1 to 12 Shore C. An outer core layer has a second surface hardness. A cover layer is formed over the outer core layer. The second outer surface hardness is greater than the geometric center hardness to define a second positive hardness gradient of about 12 to 22 Shore C.
