Abstract: Multi-layered 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 composition selected from thermoset compositions and thermoplastic compositions. The core layers have different hardness and specific gravity levels. The specific gravity (density) of the foam inner core is preferably less than the density of the outer core layer.

Abstract: The present invention relates to the use of a fatty acid (meth)acrylic acid salt in a golf ball layer. The fatty acid (meth)acrylic acid salt may be added to one or more portions of a golf ball including a core, intermediate, or cover layer. For example, in one embodiment, the fatty acid (meth)acrylic acid salt may be blended with a polybutadiene rubber material. In another embodiment, the fatty acid (meth)acrylic acid salt of the present invention may be blended with an ionomer. In some embodiments, the fatty acid (meth)acrylic acid salt may be blended with a formulation including both a polybutadiene rubber component and an ionomer.

Abstract: Method of making a golf ball comprising: providing a subassembly and a thermoset polymer composition; partially curing the thermoset polymer composition and elongating same while in a partial cure state; forming a layer about the subassembly comprising the thermoset polymer composition; and further curing the thermoset polymer composition. A moldable thermoset polymer composition may be elongated while in state of partial cure. The thermoset polymer composition may be stepwise elongated by: stretching a thermoset polymer composition in at least one plane while in partial cure state and before forming into first and second half shells; forming the thermoset polymer composition into first and second half shells and elongating the thermoset polymer composition in three dimensions while in the partial cure state and before mating the first and second half shells about the subassembly; and mating the first and second half shells about the subassembly and forming a stepwise-elongated thermoset layer.

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.
