Abstract: Golf ball comprising cast layer of thermoset polymer mixture having centering time Ct1 and comprising: (i) a polyurethane composition, polyurea composition, and/or polyurethane/polyurea hybrid composition; and (ii) a treated fumed silica compound in an amount such that centering time Ct1 is independent of the thermoset polymer mixture's degree of cure and lower than a centering time Ct2 of the thermoset polymer composition (which is dependent on its gel window Gw). The treated fumed silica compound may be surface treated with at least one of polydimethylsiloxane, hexamethyldisilazane, and dimethyldichlorosilane. In some embodiments, delta time Δt1 between a dispensing time Dt1 of the thermoset polymer mixture and centering time Ct1 is less than a delta time Δt2 between Ct1 and centering time Ct2. Centering time Ct1 and dispensing time Dt1 may differ by less than 10 seconds or even by 5 seconds or less.

Abstract: The present invention provides methods for producing molded golf balls and the resultant balls. The methods of this invention involve producing foamed polyurethane covers and these methods help reduce dimple distortions and other surface imperfections. These golf balls contain an inner core and outer foamed polyurethane cover. One or more intermediate layers can be disposed between the core and cover. In one embodiment, a castable liquid polyurethane composition containing a foaming agent is dispensed into mold cavities, which are then pressed together to form a foam cover for the ball.

Abstract: Golf ball having CoR of at least 0.700 and Atti compression of at least about 50 and comprising layer consisting of mixture of thermoset or thermoplastic composition and plurality of particulates, at least a portion surface-treated with alkoxylated siloxanes and/or polyether-modified siloxanes, and may be selected from titanium dioxide particles, barium sulfate particles, zinc sulfide particles, and/or zinc oxide particulates. At least some particulates are contacted with compound having the formula: Compound (I) may be included in amount of 0.01 to 2% by weight based on total weight of portion of plurality being contacted. The plurality may be included in mixture in amount such that layer has specific gravity of from 0.5 to about 10.0, tensile strength of from about 300 psi to about 50,000 psi, and elongation at break of from about 20% to about 1000%, each being greater than that of the thermoset or thermoplastic composition portion of the mixture.

Abstract: Multi-layered golf balls containing a dual-core structure are provided. The core structure includes an inner core (center) made from a foam or metal-containing composition, or it has a hollow shell construction, and the outer core layer is made of a thermoplastic composition. Preferably, the thermoplastic composition comprises: a) ethylene acid copolymer, b) plasticizer, and c) cation source. A fatty acid ester such as ethyl oleate is preferably used as the plasticizer. The core assembly preferably has a positive hardness gradient extending across the entire assembly. The core structure and resulting ball have relatively good resiliency at given compressions.

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: Multi-layered golf balls containing a two-layered core assembly are provided. Preferably, at least one of the core layers is formed from a thermoplastic composition that comprises: a) thermoplastic non-acid polymer, and b) plasticizer. In one preferred embodiment, the inner core is made of a first thermoplastic composition comprising the non-acid polymer and plasticizer; and the outer core layer is made of a second thermoplastic composition. For example, an ethylene acid copolymer may be used to form the outer core layer. A fatty acid ester such as ethyl oleate is preferably used as the plasticizer. Suitable non-acid polymers include, for example, polyesters, polyamides, polyolefins, and polyurethanes. The core assembly has a relatively high resiliency at given compressions.
