ABSTRACT:
The invention provides a golf ball material which includes, in mixture: (A) a metal-containing chelating agent (A1) or a mixture (A2) composed of a metal-containing chelating agent and an oxygen-containing inorganic metal compound; (B) one or more polymers selected from the group consisting of diene polymers, thermoplastic polymers and thermoset polymers; and (C) one or more acid-containing polymers having an acid content of from 0.5 to 30 wt % and selected from the group consisting of olefin-unsaturated carboxylic acid copolymers, olefin-unsaturated carboxylic acid-unsaturated carboxylic acid ester terpolymers, unsaturated carboxylic acid anhydride-containing polymers, unsaturated dicarboxylic acid-containing polymers and unsaturated dicarboxylic acid half ester-containing polymers. The invention also provides a method for preparing such a golf ball material, and a golf ball made with the material. The golf ball material has a good thermal stability, flow and processability, making it suitable for injection molding. Moreover, this material is ideal for producing, without any loss in the rebound resilience of golf ball parts molded from the material, high-performance golf balls endowed with excellent durability, scuff resistance and flexibility.
