Golf ball incorporating grafted metallocene catalyzed polymer blends

Abstract

Golf balls having at least one layer formed from compositions including at least one of a polyamide, in the form of a homopolymer, a copolymer or mixtures thereof, or an olefinic polymer produced using a single-site metallocene catalyst in the polymerization process, to which at least one pendant functional group has been grafted by a post-polymerization reaction. The polyamide compositions may be mixed with ionomers or non-ionomers, including grafted or non-grafted metallocene catalyzed polymers. The grafted metallocene catalyzed polymer compositions may be mixed with at least one of an ionomer, a non-grafted or unfunctionalized metallocene catalyzed polymer, polyamide, or other non-ionomeric polymer to form a blend. The compositions may be used in any layer of a golf ball, and may be foamed or unfoamed.
