摘要： The invention provides a golf ball material comprising components (A), (B) and (C): (A) a mixture of different masterbatches prepared by separately masterbatching two or more different metal ions (A1) or a masterbatch prepared by simultaneously masterbatching two or more different metal ions in itself (A2), (B) one or more polymer selected from the group consisting of diene polymers, thermoplastic polymers and thermoset polymers, and (C) one or more polymer having an acid content of from about 0.5 to about 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 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 of 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 of the rebound resilience of golf ball parts molded from the material, high-performance golf balls having excellent durability, scuff resistance and flexibility.

摘要： The invention provides a golf ball material composed of an ionomeric resin composition obtained by melt-blending under applied heat one or more compounds selected from among UV/EB-curable materials with, in the presence of a peroxide, a non-ionomeric thermoplastic resin and an ionomeric resin; or of an ionomeric resin composition obtained by using, instead of the ionomeric resin, an acid-containing polymer base of the ionomeric resin and subjecting the acid-containing polymer composition similarly prepared by melt-blending under applied heat to an acid-neutralizing reaction with a metal ionic species. Methods for preparing such a material, and golf balls which include as a component therein a molding made of the golf ball material are also provided. The golf ball material has a good thermal stability, flow and processability, and can thus be used to obtain high-performance golf balls endowed with an excellent abrasion resistance, scuff resistance, durability and flexibility without a loss of rebound.

摘要： Solid golf balls comprise a vulcanizable rubber and a reinforcing filler comprising an essentially anhydrous metal salt of an .alpha.,.beta.-ethylenically unsaturated carboxylic acid. Golf balls containing such reinforcing fillers have improved physical properties over rubber compounds containing conventional metal carboxylic acid salts. Additionally, the rubber compounds have improved processability and shorter curing time.
