发明名称 MULTI-LAYER GOLF BALL AND COMPOSITION
摘要 A multi-layer golf ball comprising a core, a cover layer and a mantle layer disposed between the core and the cover. The cover layer consists essentially of at least a first and a second ionomer resin. The first resin is a copolymer of 16 to 35 % by weight of an alpha, beta-unsaturated carboxylic acid and 84 to 65 % by weight of an olefin, wherein about 10 to about 90 % of the carboxyl groups of the copolymer are neutralized with a metal ion. The second resin is a terpolymer of 9 to 12 % by weight of an alpha, beta-unsaturated carboxylic acid, 1 to 50 % by weight n-alkyl acrylate or methacrylate and 38 to 90 % by weight of an olefin, wherein about 10 to about 90 % of the carboxyl groups of the terpolymer are neutralized with a metal ion. The mantle layer comprises a thermoplastic material, said thermoplastic material consisting essentially of polyetherester block copolymer.
