US 2013/0157779 A1 · GOLF BALL COMPOSITION

Abstract

This invention pertains to a golf ball which includes a core, optionally one or more intermediate layers; and an outer cover layer. The outer cover layer and/or one or more intermediate layers includes a blend of a) 2 to 60 wt % (based on the total weight of the blend composition) of a cyclic olefin polymer which includes a norbornene-based monomer having the general formula; where R18 to R21 independently represent a hydrogen atom, a halogen atom or a hydrocarbon group and m is from 0 to about 3; and b) about 40 to about 98 wt % (based on the total weight of the blend composition) of one or more additional polymer components. The blend composition has a melt flow index (MFI) from 1 to 80 g/10 min., a material hardness of 30 to 90 Shore D, and a flex modulus of 10 to 120 kpsi.
