Abstract:
1. A golf ball material comprising: (A) a metal ionic species in a form of (A2) a master batch of an oxygen-containing inorganic metal compound having an average particle size of 0.005 to 50 μm and a particle size distribution of 0.001 to 300 μm in diameter, (B) at least one polymer selected from the group consisting of 1,4-polybutadiene, polystyrene elastomers, polyacrylate polymers, polyurethane elastomers, polyester elastomers, polyacetals, epoxy resins, unsaturated polyester resins, silicone resins and ABS resins, and (C) at least one acid-containing polymer having an acid content of 0.5 to 30% by weight and selected from the group consisting of olefin-unsaturated carboxylic acid copolymers, olefin-unsaturated carboxylic acid-unsaturated carboxylic acid ester terpolymers, and polymers containing one or more monomer selected from the group consisting of unsaturated carboxylic anhydrides, unsaturated dicarboxylic acids and half esters thereof, the component (C) being un-neutralized; which is obtained by preparing a polymer blend of component B and component C, then blending component A together with the polymer blend.
