ABSTRACT:
The present invention is directed to a golf ball cover comprising a blend of copolymers wherein one or more of the copolymers is a low cost non-ionic copolymer and one or more of the copolymers is an ionic copolymer. Surprisingly, a golf ball cover comprising the non-ionic/ionic copolymer blend exhibits no loss in C.O.R., and has equal resistance to cutting and cracking when compared to top grade golf ball covers made with one of the conventional 100% ionic copolymer blends. In particular, the present golf ball cover comprises from about 95 to about 80 pphr of one or more ionic copolymers, and from about 5 to about 20 pphr of one or more non-ionic copolymers, the latter being selected from the group consisting of a copolymer or terpolymer of ethylene or propylene; acrylic acid or methacrylic acid; a lower alkyl acrylate, and blends thereof.
