Abstract
Multi-piece golf balls having at least one layer made from a polyamide non-ionomeric composition are provided. The polyamide composition consist essentially of about 40 to about 99% by weight polyamide; about 1 to about 60% by weight of an acid anhydride-modified polyolefin; and about 1 to about 60% of a fatty acid additive selected from the group consisting of fatty acid salts, fatty acid amides, and mixtures thereof. The ball includes a core, preferably a dual core construction; and a cover of at least one layer. A rubber composition is preferably used to form the inner core and the polyamide composition is preferably used to form the outer core layer. The resulting ball has high resiliency along with a soft feel.
