Abstract: Multi-piece golf balls having a solid core and cover are provided. The ball contains a small, heavy inner core and surrounding outer core layer. The inner core preferably contains metal materials such as copper, steel, brass, tungsten, titanium, nickel, iron, tin, and bronze particles dispersed in a thermoset or thermoplastic polymeric matrix. Preferably, the polymeric matrix comprises polybutadiene rubber. The outer surface of the inner core preferably has a non-uniform structure and includes projecting members. For example, the outer surface may contain multiple projecting ribs with gaps located between the ribs. The ball includes a cover surrounding the core structure. The cover may be multi-layered.

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: Golf balls having a very high positive gradient multilayer core are provided. The multilayer core includes an outer core layer and a very soft, low compression inner core layer. The inner core layer is formed from an unfoamed composition and has a center hardness that is at least 40 Shore C points less than the outer surface hardness of the outer core layer.

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.

L1 is formed from at least one highly neutralized polymer and has first specific gravity SG1; L2 is formed from at least one partially neutralized polymer and has second specific gravity SG2; and L3 is formed from at least one of a thermoset or thermoplastic composition and has third specific gravity SG3. At least two of SG1, SG2, and SG3 is less than 1.13 g/cc. SG1 may be less than 1.13 g/cc, or less than 1.0 g/cc.

Abstract: Multi-piece golf balls containing a dual-layered core structure 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 layers of the core structure may have different hardness gradients. The center of the core comprises a metal material such as copper, steel, brass, tungsten, titanium, aluminum, and alloys thereof dispersed in a thermoset polymeric matrix. The outer core layer is preferably formed from a thermoplastic composition such as an ethylene acid copolymer ionomer resin. The resulting ball has high resiliency and good spin.
