ABSTRACT:
A golf ball material composed of (A) an ionomer, (B) a resin composition which includes one or more selected from the group consisting of diene polymers, thermoplastic polymers and thermoset polymers, and (C) an acid group-bearing thermoplastic resin composition is prepared by melt-mixing components B and C so as to form a resin composition of components B and C, then melt-mixing this resin composition with component A while injecting water under pressure. The golf ball material has a good thermal stability, flow and processability, and can be used to produce high-performance golf balls endowed with durability, scuff resistance and optimal hardness without a loss of rebound.
