    Abstract: 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.

    Abstract: Golf ball comprising layer formed from polymer composition comprising delignified natural wood. The delignified natural wood may be basswood, oak, poplar, ash, alder, aspen, balsa wood, beech, birch, cherry, butternut, chestnut, cocobolo, elm, hickory, maple, oak, padauk, plum, walnut, willow, yellow poplar, bald cypress, cedar, cypress, fir, hemlock, larch, pine, redwood, spruce, tamarack, juniper, yew, and/or bamboo and having a lignin content of less than 20 wt %. Hemicellulose content may be less than 30 wt %, or about 15 wt % or less, or less than 15 wt %. The delignified natural wood is included in the polymer composition in an amount of 20 wt % or less, based on total weight of the polymer composition. Examples of polymer compositions include rubbers, polyurethanes, polyureas, ionomers, and combinations thereof. In specific embodiments, the golf ball core and/or intermediate layer is formed from the polymer composition. The delignified wood may comprise chopped wood pieces and/or powder.

    Abstract: Golf ball comprising a core, an outer layer and at least one adhesion promoting coating disposed between each of the core and the outer layer; the core comprising a rubber composition comprising at least one zinc-containing and/or magnesium-containing component; the outer layer comprising at least one ionomer; and the adhesion promoting coating comprising a waterborne dispersion comprised of at least one ethylene acid copolymer having an acid content of at least 15% by weight wherein the copolymer is at least partially neutralized with one or more neutralizing agent; wherein at least one neutralizing agent is selected from ammonia compounds and/or amine compounds. In a specific embodiment, the at least one neutralizing agent comprises i) mono and/or divalent metal compounds and ii) ammonia compounds and/or amine compounds.
