The present invention relates to
golf ball having a core and an outer cover layer 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 % (based on the combined weight of Components A and B) of either one or more unimodal acidic polymers; or a bimodal
polymer blend composition including a high molecular weight component having a weight average molecular weight, Mw, of about 80,000 to about 500,000 and including one or more
ethylene / α,β-ethylenically unsaturated C3-8
carboxylic acid copolymers and / or one or more
ethylene,
alkyl (
meth)
acrylate, (
meth)
acrylic acid terpolymers; and a low molecular weight component having a weight average molecular weight, Mw, of about from about 2,000 to about 30,000 and comprising one or more
ethylene / α, β-ethylenically unsaturated C3-8
carboxylic acid copolymers and / or one or more ethylene,
alkyl (
meth)
acrylate, (meth)
acrylic acid terpolymers. Also included in the blend is one or more basic
metal salts present in an amount to neutralize at greater than or equal to about 30 percent of the acid groups of the acid
polymer. 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 Shire D
hardness as measured on the ball of from about 35 to about 70 and a shear
cut resistance of less than about 4.
