Abstract:
Multi-piece golf balls having a solid core of at least one layer and cover of at least one layer are provided. At least one of the core layers comprises a thermoplastic ionomer composition, preferably a highly neutralized ethylene acid copolymer. And, at least one of the core layers comprises a thermoplastic polyamide composition. The ionomer composition is preferably used to form the inner core and the polyamide composition is preferably used to form the outer core layer. More preferably, the ionomer composition has a flex modulus of 80,000 psi or less and the polyamide composition has a flex modulus of 90,000 psi or greater. The resulting ball has high resiliency and rebounding properties.
