Abstract:
1. A method for preparing a golf ball material composed of (A) a metal ionic species in the form of one or both (A1) ultrafine particles and (A2) a master batch, (B) at least one polymer selected from the group consisting of diene polymers, thermoplastic polymers and thermoset polymers, and (C) at least one acid-containing polymer having an acid content of 0.5 to 30% by weight, 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 comprises the steps of: (a) preparing a polymer blend of component B and component C; and (b) using component A1 or component A2 or both components A1 and A2 to carry out in one step a neutralization reaction on the acid groups contained in the polymer blend of components B and C, wherein the ultrafine particles (A1) have an average particle size of from 0.005 to 0.1 μm and a particle size distribution of 0.001 to 1.0 μm, the metal ionic species in the form of (A2) a master batch have an average particle size of 0.005 to 50 μm and a particle size distribution of 0.001 to 300 μm and component B is at least one polymer selected from the group consisting of polystyrene elastomers, polyacrylate polymers, polyurethane elastomers, polyester elastomers, 1,4-polybutadiene, polyacetals, epoxy resins, unsaturated polyester resins, silicone resins and ABS resins.
