Abstract
Disclosed herein are a novel thermoplastic material and a golf ball utilizing the thermoplastic material of the invention. The golf ball (10) preferably comprises a core (12), a cover (16) and, optionally, a boundary layer (14). At least one of the core (12), cover (16) or boundary layer (14) of the golf ball (10) comprises a thermoplastic material according to the invention. A thermoplastic material of the invention comprises a partially to highly neutralized blend of an acid copolymer, a copolymer comprising a metallocene-catalyzed alpha-olefin and a softening comonomer, and a fatty acid or fatty acid salt.
