Golf ball incorporating polymer composition comprising: (i) a reaction mixture of ethylene-acid copolymer and C3-8 α, β-ethylenically unsaturated carboxylic acid(s); and (ii) poly-hydroxy crosslinking agent(s) such as polyvinyl alcohol, diols, glycols, sugar alcohols, and/or glycerols. Concentration of poly-hydroxy crosslinking agent(s) in polymer composition may be up to about 10% (or up to about 5%, or from 0.1% to about 2.5%, or from about 0.05% to 0.95%), by weight, based on 100% total weight of polymer composition. Reaction mixture may further comprise cation source and optionally organic acid(s) or salt thereof. Reaction mixture or polymer composition may include adjuvant(s). such as a silane compound, for example N-(2-aminoethyl-3 aminopropyl)trimethoxysilane and/or 3-glycidoxypropyl trimethoxysilane, in concentration of from 0.025% to 1.0% by weight, based on 100% total weight of reaction mixture or in concentration of up to 10% by weight, based on 100% total weight of the polymer composition. |
