Polyamide-ionomer graft copolymer and blends thereof for use in golf ball covers or mantles |
摘要 |
Disclosed herein is a golf ball with a cover or mantle, or both, formed from a composition comprising a polyamide-ionomer graft copolymer and a method of making the same. Polyamide-ionomer graft copolymers include a polyamide component and an ionomeric component. In a preferred form, polyamide-ionomer graft copolymers have a polyamide component backbone and ionomeric components grafted thereto. Golf balls according to the invention may also be formed from a composition or material that includes a blend of a polyamide-ionomer graft copolymer and an ionomer. Such blends are preferably employed as a mantle or a cover of a golf ball. The cover composition has excellent durability and resistance to cracking, even at cold temperatures. Materials comprising polyamide-ionomer graft copolymer are a useful substitute for an ionomer golf ball cover, particularly when a low spin golf ball is desired.
