US 7,528,196 B2 · Polyalkenamer compositions and golf balls prepared therefrom

Abstract

A golf ball that includes (a) a core comprising a center; (b) an outer cover layer; and (c) one or more intermediate layers; wherein at least one of the core, the outer cover layer, or the intermediate layer comprises a composition that includes (i) at least one polyalkenamer and at least one polyamide or (ii) at least one polyalkenamer. A method for making a golf ball comprising a core, one or more intermediate layers and an outer cover layer is also disclosed, wherein the method includes forming a blend comprising at least one polyalkenamer rubber and at least one polyamide; and injection molding the blend into a spherical mold to form the intermediate or outer cover layer. Also disclosed is a polymer composition that includes at least one polyalkenamer and at least one thermoplastic copolyamide elastomer.
