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.
