Abstract
The invention provides a golf ball cover stock based on a heated mixture of (a) an ionomer resin, (b) polyethylene, and (c) an epoxy group-modified polyolefin or (d) a low molecular weight polyethylene wax. Component (c) or (d) improves the dispersion of polyethylene in the ionomer resin so that a larger amount of polyethylene may be blended in micro-dispersion form. A golf ball having a cover made of the cover stock is durable and wear resistant and offers a good feel when hit.
