In a golf ball comprising a core and a cover of one or more layers, the cover or its layer is formed primarily of a mixture comprising a blend of (a) an ionomer resin in the form of a divalent metal-neutralized ethylene-acrylic acid copolymer and (b) an olefin-unsaturated carboxylic acid copolymer or an olefin-unsaturated carboxylic acid-unsaturated carboxylate copolymer, (c) a thermoplastic elastomer, (d) a fatty acid or derivative thereof having a molecular weight of 280 to 1,500, and (e) a basic metal compound. The mixture is thermally stable, flowable and easy to mold and the ball has improved rebound, feel and durability. |
