PROBLEM TO BE SOLVED: To provide a resin composition for golf balls with superior resilience, flexibility and fluidity, and to provide a golf ball with superior resilience and driving feeling.SOLUTION: The resin composition for golf balls comprises: (A) at least one selected from a group consisting of (a-1) a binary copolymer of an olefin and an α,&bgr;-unsaturated carboxylic acid having 3 to 8 carbon atoms, (a-2) a metal ion-neutralized product of a binary copolymer of an olefin and an α,&bgr;-unsaturated carboxylic acid having 3 to 8 carbon atoms, (a-3) a ternary copolymer of an olefin, an α,&bgr;-unsaturated carboxylic acid having 3 to 8 carbon atoms, and an α,&bgr;-unsaturated carboxylic acid ester, and (a-4) a metal ion-neutralized product of a ternary copolymer of an olefin, an α,&bgr;-unsaturated carboxylic acid having 3 to 8 carbon atoms, and an α,&bgr;-unsaturated carboxylic acid ester; (B) a compound containing a hydrocarbon chain, a cationic moiety, and an anionic moiety in its molecule; and (C) a nonionic surfactant. A total degree of neutralization expressed by the following equation is 50-300 mol%. |
