ABSTRACT:
A golf ball material composed of (A) an olefin-containing thermoplastic polymer having an acid content of at least 0.5 wt % but less than 5.0 wt %, (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 oxygen-containing inorganic metal compound has a good thermal stability, flow and processability, making it suitable for injection molding. The golf ball material is ideal for the production of high-performance golf balls endowed with durability, scuff resistance and optimal hardness without a loss of rebound in the molded article.
