Abstract

A composition suitable for molding a cover for a golf ball, said cover having a Shore C hardness less than substantially 85 (but optionally in the range 70 to 85) comprises: (1) a thermoplastic urethane having a Shore A hardness less than substantially 95; and (2) an ionomer comprising olefinic groups having 2 to 4 carbon atoms copolymerized with a monocarboxylic acid having 3 or 4 carbon atoms, said acid groups being at least partly neutralized with metal ion(s), said ionomer having a Shore D hardness at least substantially 55. The cover improves characteristics of a golf ball, especially of golf balls having molded spherical cores, e.g. spin rate, short iron and wood playability, puttability, and durability.
