摘要： A formulation for making at least one element of a golf ball, wherein the formulation includes: (i) from 50 weight percent to 95 weight percent of a thermoplastic composition comprising: (1) at least one ethylene acid copolymer consisting essentially of copolymerized comonomers of: (A) ethylene, and (B) from 5 weight percent to 25 weight percent of at least one α,β-ethylenically unsaturated carboxylic acid having from 3 carbon atoms to 8 carbon atoms, based on the total weight of monomers present in the ethylene acid copolymer; wherein the acid moieties of component (1) are neutralized to a level of from 25 percent to 220 percent; and (ii) from 5 weight percent to 50 weight percent of a crosslinked material having a gel content of at least 80 weight percent, wherein the crosslinked material is a crosslinked elastomer, a crosslinked rubber, or a blend of a crosslinked elastomer and a crosslinked rubber; a process for making the above formulation; at least one element of a multilayer golf ball and a process for making the at least one element of a multilayer golf ball using the above formulation; a multilayer golf ball including (a) at least one core, and (b) a cover; wherein the at least one core is made from the above formulation; and a process of manufacturing the above multilayer golf ball.
