Abstract: Golf ball comprising layer(s) comprised of plasticized neutralized acid polymer composition consisting of mixture of: (a) low molecular weight acid-containing wax(es); (b) non-acid-polymer(s) including at least one low molecular weight non-acid wax such as high density oxidized polyethylene homopolymers; ethylene maleic anhydride copolymers; polypropylene maleic anhydride copolymers; polypropylene homopolymers; ethylene-vinyl acetate copolymers; high density oxidized homopolymers; oxidized copolymers; polyethylene micronized waxes; polytetrafluoroethylene micronized waxes; emulsifiable low molecular weight non-acid waxes; non-emulsifiable low molecular weight non-acid waxes; and/or chemically modified low molecular weight non-acid waxes; (c) organic acid(s) or salt thereof; and (d) plasticizer(s). Molecular weight of each low molecular weight acid-containing wax is about 500 to 7000, or up to 30,000. Interactions between components (a), (b), (c) and (d) advantageously produce layer of ionomeric material having heat stability, processability, and well-retained durability, adhesion, CoR, compression and softer feel without need for blending high and low molecular weight acid-containing polymer(s).

Abstract: Multi-layered golf balls containing a three-layered cover assembly are provided. For example, a cover assembly having an inner cover, intermediate cover, and outer cover layer may be prepared. At least one of the cover layers is formed from a thermoplastic composition that preferably comprises: a) thermoplastic non-acid polymer, and b) plasticizer. 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 cover assembly has good impact durability and helps provide the ball with relatively high resiliency at given compressions.

Abstract: Multi-layered golf balls having a core made of a foamed composition, preferably polyurethane foam, are provided. The ball includes a dual-layered core having a foam inner core (center) and surrounding outer core layer. The outer core layer may be made from a non-foamed thermoset material such as polybutadiene rubber. The ball further includes an inner cover, preferably made from an ionomer composition comprising an O/X-type acid copolymer, wherein O is α-olefin, and X is a C3-C8 α,β-ethylenically unsaturated carboxylic acid. The outer cover may be made from a non-foamed thermoset or thermoplastic material such as polyurethane. Preferably, the specific gravity of the inner cover is greater than the specific gravity of the outer core, which is greater than the specific gravity of the inner core. The finished ball has good distance and low-spin properties.

Abstract: Multi-layered golf balls having at least one layer made of a polyamide composition containing a plasticized polyamide are provided. In one preferred version, the polyamide composition consists essentially of a polyamide and plasticizer selected from the group consisting of polytrimethylene ether glycol and polytrimethylene ether glycol benzoate and monomers, oligomers, copolymers and blends thereof. Blends of plasticized polyamides and ethylene acid copolymer ionomers also can be prepared. The golf ball includes a core having at least one layer and a cover having at least one layer. The polyamide composition may be used to form any core, cover, or other layer in the golf ball. The polyamide compositions have a good combination of properties including Coefficient of Restitution (COR) and compression.

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: Golf balls having covers made of thermoplastic polyurethane compositions are provided. Multi-piece golf balls can be made. In one embodiment, the outer cover layer is formed from a composition comprising a thermoplastic polyurethane and acid copolymer ionomer. The cover composition also can contain hydroxyl-containing compounds. The golf ball having the thermoplastic polyurethane cover can be treated with an isocyanate compound. The golf ball also can be treated with a hydroxyl and/or silane-containing compound. The cover composition and surface coatings can further include catalysts, ultraviolet (UV)-light stabilizers, and other additives. The coating methods have many benefits and the finished balls have good physical properties.

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 Da may differ by less than 10 seconds or even by 5 seconds or less.

Abstract: Multi-layered golf balls having a core made of a foamed composition, preferably polyurethane foam, are provided. The ball includes a dual-layered core having a foam inner core (center) and surrounding outer core layer. The outer core layer may be made from a non-foamed thermoset material such as polybutadiene rubber. The ball further includes an inner cover, preferably made from an ionomer composition comprising an O/X-type acid copolymer, wherein O is α-olefin, and X is a C3-C8 α,β-ethylenically unsaturated carboxylic acid. The outer cover may be made from a non-foamed thermoset or thermoplastic material such as polyurethane. Preferably, the specific gravity of the inner cover is greater than the specific gravity of the outer core, which is greater than the specific gravity of the inner core. The finished ball has good distance and low-spin properties.
