    Abstract: Casing compositions including carboxylic acid groups, cover compositions including an adhesion promoter with functional groups that crosslink with carboxylic acid groups, and golf balls made from such compositions that have crosslinks between functional groups of the cover compositions and the carboxylic acid groups. The type and concentration of the components in the casing and cover compositions, including the adhesion promoter, affect the adhesion between golf balls having components made from such compositions and, thus, can be used to produce a golf ball having increased durability. Additionally, methods of crosslinking casing and cover layers made from such casing and cover compositions to increase interlayer adhesion are disclosed.

    Abstract: Golf ball incorporating polyurethane mixture having wt. % NCO content of ˜4-20 and including a prepolymer polyol portion comprised of trans-β-Farnesene diol(s) in an amount of about 3-70 wt. % of total weight of prepolymer. Trans-β-Farnesene diol may be 15 carbon, long chain, branched, unsaturated 3,4-vinyl-containing bio-hydrocarbon having the formula: Prepolymer can include a 1:99 to 99:1 blend (wt. % ratio) of Trans-β-Farnesene diol(s) and polybutadiene-based polyol(s) in an amount of about 35-85 wt. %, along with about 15 wt. %-65 wt. % of diisocyanate(s). Curative may be combined with prepolymer in amount of about 3-25 wt. % of total weight of curative and prepolymer combined, and may be mixture of aromatic diamine(s) and white dispersion in a wt. % ratio of about 90:10 to 50:50, plus catalyst. Hardness of polyurethane mixture can be from 75. Shore A to 75 Shore D or a material hardness can be from about 40 Shore D to about 65 Shore D.

    Abstract: Multi-piece golf balls having a solid core made of a foamed composition and a cover are provided. Preferably, the core is dual-layered having has a foam inner core (center) and surrounding thermoset or thermoplastic outer core layer. Preferably, a polyurethane foam composition containing mineral filler particulate, for example, nanoclay particles, is used to form the foam center. The concentration of clay particulate is preferably in a range of 0.1 to 60% by weight. The surrounding outer core layer may be made from non-foamed or foamed compositions. For example, polybutadiene rubber or highly neutralized olefin acid copolymers may be used in the outer core layer. The core layers have different hardness gradients and specific gravity values.
