PROBLEM TO BE SOLVED: To provide a resin composition for golf balls which has excellent flexibility, fluidity, and resilience, and golf balls using the resin composition.SOLUTION: A resin composition for golf balls includes a polymer that contains a diene polymer moiety and a carboxylic acid-based moiety, and in which carboxyl groups derived from the carboxylic acid-based moiety are neutralized. In the resin composition for golf balls, the polymer is obtained by neutralizing the carboxyl groups derived from an unsaturated carboxylic acid compound contained in a reaction product of the C2-C18 unsaturated carboxylic acid compound and the dien polymer having an α,&bgr;-unsaturated carbonyl group at each end. |
