  • Resin composition for golf ball and golf ball
    Patent number: 9006346
    Abstract: The present invention provides a resin composition for a golf ball and a golf ball which have high resilience while maintaining soft compression and also have low spin on driver shots, and therefore can achieve a long flight distance. The present invention relates to a resin composition for a golf ball, including an ionomer resin consisting of a metal ion-neutralized copolymer of (A) a C3-8 ?,?-unsaturated carboxylic acid and (B) a C3-8 ?,?-unsaturated carboxylic acid ester, the ionomer resin having a mass ratio of (A)/(B) of 10/90 to 25/75, and a degree of neutralization of 30 to 105 mol %.
