Golf balls incorporating HNP ionomers based on highly diverse mixtures of organic acids

Abstract

Golf ball incorporating an HNP composition consisting of a mixture of: at least one ethylene acid copolymer; sufficient amount of cation source to neutralize greater than about 100% of all acid groups present; and a highly diverse mixture of at least four organic acids having different characteristics such as relating to: carbon chain lengths, number of double bonds on carbon chains, positioning of double bonds on carbon chains, number of branches, types of branches, positioning of branches on carbon chains, positioning of acid groups on carbon chains, configurations (cis/trans), functional groups on carbon chains, being saturated/unsaturated, being conjugated/non-conjugated; presence/absence of functional group(s) on carbon chain; being aliphatic/aromatic, or combinations thereof. No organic acid is present in highly diverse mixture in a concentration greater than 80%, or, in some embodiments, greater than 60%, or greater than 40%. HNP composition may be relatively soft/relatively low modulus, relatively hard/relatively high modulus, or blends thereof.
