<p>Disclosed herein is a game ball and method for making the same. The game ball has an unneutralized terpolymer resin cover that has been irradiated. The unneutralized terpolymer resin includes ethylene, acrylic or methacrylic acid, and a third component selected from the group of lower alkyl acrylates and lower alkyl methacrylates. The irradiated unneutralized terpolymer resin cover is superior in at least one of cut resistance and scuff resistance to a cover substantially identical in composition but which has not been irradiated. The game ball cover of the invention is particularly useful for improving the durability of golf balls to be struck with sharp-grooved clubs.</p> |
