A two piece ball golf ball having a core, and an outer cover layer or a ball having a core, an outer cover layer; and one or more intermediate layers, where at least one of the outer cover layer, or intermediate layer is made from a blend composition of about 1 to about 99 wt % of a block copolymer having no polar functionality; and from about 1 to about 99 wt % of an ionomer. Also included in the blend is from about 0.5 to about 10 pph ((based on the combined weight of the block copolymer and ionomer) of a compound having the general formula: (R2N)m—R′—(X(O)nORy)m, where R is hydrogen, or a C1-C20 aliphatic, cycloaliphatic or aromatic group; R′ is a bridging group comprising one or more C1-C20 straight chain or branched aliphatic or alicyclic groups, or one or more C1-C20 substituted straight chain or branched aliphatic or alicyclic groups, or one or more C1-C20 aromatic groups, or an oligomer of up to 12 repeating units including, but not limited to, polypeptides derived from an amino acid sequence of up to 12 amino acids; and X is C or S or P with the proviso that when X═C, n=1 and y=1 and when X═S, n=2 and y=1, and when X═P, n=2 and y=2; and m=1-3. The blend composition has a melt index of greater than about 5 g/10 min, a flexural modulus of from about 500 to about 100,000 psi, a material Shore D hardness of from about 25 to about 70; and the golf ball has a cover layer Shore D hardness as measured on the ball of from about 35 to about 70 and a shear cut resistance of less than about 4.
