Abstract
An object of the present invention is to provide a golf ball resin composition with an excellent resilience and fluidity. Another object of the present invention is to provide a golf ball resin composition with a high hardness and durability. Yet another object of the present invention is to provide a golf ball traveling a great distance with an ionomer cover. The present invention provides a golf ball resin composition comprising, (A) an ionomer resin consisting of a metal ion-neutralized product of a binary copolymer composed of an olefin and an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms; (B) a binary copolymer composed of an olefin and an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms, and (C) a zinc compound, wherein a content ratio ((A)/(B)) of (A) component to (B) component ranges from 50/50 to 80/20 in a mass ratio and a content of (C) component ranges from 0.1 part to 20 parts with respect to 100 parts by mass of a sum of (A) component and (B) component, and the golf ball resin composition has a melt flow rate (190° C., 2.16 kg) of 15 g/10 min or more.
