GAME BALL WITH SOFT, RADIATION CROSS-LINKED COVER CONTAININGUNNEUTRALIZED TERPOLYMER

摘要

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