(57) [PROBLEMS] To provide a resin composition for golf balls, which is flexible and has excellent resilience and durability. SOLUTION: A golf ball cover is formed by using a composition comprising a molten mixture of an ionomer resin, a partially saponified ethylene / unsaturated carboxylic acid ester copolymer, and a polymer having a maleic anhydride group. As a result, it is possible to obtain a golf ball which is flexible and has excellent resilience and durability. |
