Golf balls having a single or dual-layered solid core are provided. In one embodiment, the golf ball has dimensions and properties that do not conform to the rules of the United States Golf Association (USGA). For example, the ball weight; ball size; ball spherical symmetry; ball initial velocity; and/or ball overall distance may fall outside of the USGA standards. The dual-layered core can have an inner core comprising a thermoplastic composition and surrounding outer core comprising a thermoset composition. In another embodiment, the dual-layered core has an inner core comprising a thermoplastic composition and outer core comprising a thermoset composition. The thermoplastic composition preferably comprises an ethylene acid copolymer ionomer and plasticizer. The thermoset composition preferably comprises polybutadiene rubber. The ball further includes a cover of at least one layer.

Non-conforming golf balls made from plasticized thermoplastic materials

Golf ball having at least one layer formed from a thermoset or thermoplastic composition comprising one or more free radical scavengers selected from lignosulfonates, hydroxycarboxylic acids, carbohydrates, superplasticizers, or combinations thereof.

Buoyant high coefficient of restitution (CoR) golf ball incorporating aerodynamics targeting flight trajectory

Golf ball comprising one or more layers and/or indicia formed from a fluorescent composition comprising: a base polymer; and a colorant; wherein the colorant is a small-molecule ionic isolation lattice formed from one or more fluorescent dye and one or more cyanostar macrocycles. The one or more fluorescent dyes may include at least one dye selected from xanthenes, oxazines, styryls, cyanines, trianguleniums, or mixtures thereof. The colorant may be a dispersion of the small-molecule ionic isolation lattice in a carrier medium or a powder. In particular embodiments, at least one of the one or more layers is a cover layer and/or a coating layer.

Golf ball having CoR of at least 0.810, specific gravity SGof less than 1.00 g/cc, and initial velocity of at least 250 ft/s and comprising a first layer L, a second layer Lsurrounding L, and a third layer Lsurrounding L. Lis formed from at least one highly neutralized polymer and has first specific gravity SG; Lis formed from at least one partially neutralized polymer and has second specific gravity SG; and Lis formed from at least one of a thermoset or thermoplastic composition and has third specific gravity SG. At least two of SG, SG, and SGis less than 1.13 g/cc. SGmay be less than 1.13 g/cc, or less than 1.0 g/cc. The thermoset or thermoplastic composition may comprise polyurethane(s), polyurea(s), polyurethane(s)/polyurea(s) hybrids, and/or ionomers such as at least partially neutralized polymers and/or HNPs.

Buoyant, high coefficient of restitution (CoR) golf ball having a reduced flight distance yet the perceived flight trajectory of regular distance high CoR golf balls

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.

Golf balls having foam inner core and thermoset outer core layer

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.

Golf balls having dual-layered cores with metal-containing centers and dual-layered covers

Golf balls comprising a multi-layer core and a cover are disclosed. The multi-layer core comprises at least three layers, including at least one thermoset layer and at least one thermoplastic layer. The innermost core layer is relatively small, having a diameter of from 0.50 inches to 1.30 inches.

Multi-layer core golf ball

Multi-layered, golf balls having a core made of a foamed composition are provided. The core preferably has a foam inner core (center) and surrounding thermoset or thermoplastic outer core layer. Preferably, a polyurethane foam composition comprising secondary blowing agents that are activated by heat is used to form the foam center. Non-foamed thermoset materials such as polybutadiene rubber may be used to form the outer core layer. The core layers have different hardness gradients and specific gravity values. The foam cores have good resiliency, thermal stability, and durability over a wide temperature range. The ball further includes a cover that may be multi-layered.

Golf balls containing multi-layered cores with heat-activated foam center

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.
