Golf ball cover

A composition suitable for molding a golf ball cover comprising 80-50% by weight of a high stiffness ionomer and 20-50% by weight of a very low modulus ionomer, wherein said high stiffness ionomer is a copolymer of 75-80% of an olefin with 20-25% of an alpha, beta ethylenically unsaturated carboxylic acid having 10-90% of the carboxylic acid groups neutralized with sodium, lithium, zinc or magnesium ions and has a flexural modulus from about 75,0.00 to about 120,000 psi and a shore D hardness of 70 or greater and the very low modulus ionomer is a terpolymer of 67-70% by weight ethylene, 20-23% by weight n- or iso-butyl acrylate and 10% by weight methacrylic acid, where 10-90% of the acid groups are neutralized by sodium, zinc or lithium ions and has a flexural modulus from about 2,000 to 8,000 psi and a shore D harness of 20-50.
