ABSTRACT:
The disclosed invention provides a golf ball including a core and a cover of at least two layers, wherein the at least one cover layer includes an inner cover layer of at least one ionomer resin and an outer cover formed from a polymer blend including at least one grafted metallocene-catalyzed polymer and at least one ionomer neutralized with a metal cation, and optionally, a non-grafted metallocene-catalyzed polymer.
