Abstract:
1. A golf ball material comprising a thermoplastic ionomer blend composition of thermoplastic components (a), (b) and (c) below neutralized with (d) metal cations: (a) at least one E/X/Y terpolymer having a polystyrene equivalent weight-average molecular weight Mw at least about 100,000, measured by gel permeation chromatography (GPC), wherein E is an α-olefin, X is a C (b) at least one E/X copolymer and/or E/X/Y terpolymer having a polystyrene equivalent weight-average molecular weight Mw about 1,500 to about 95,000 measured by GPC, wherein X is present in an amount of from about 1 to about 30 wt % of the E/X copolymer or E/X/Y terpolymer and Y is present in an amount of from about 2 to about 30 wt % of the E/X/Y terpolymer, component (b) being present in an amount of from about 5 to about 45 wt % based on the total weight of components (a), (b) and (c) combined; and (c) at least one mono- and/or multifunctional acid groups-containing organic compound, or a metal salt thereof, having a molecular weight of less than about 1,000, component (c) being present in an amount of about 5 to about 35 wt % based on the total weight of components (a), (b) and (c) combined.
