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.
A golf ball comprising:
The golf ball according to claim I, wherein said polyamide-ionomer graft copolymer includes a backbone comprising a polyamide component and a plurality of ionomeric components grafted to said backbone.
The golf ball according to claim I, wherein said ionomeric component is an ionomeric copolymer comprising an alpha-olefin having 2 to 8 carbon atoms, and an alpha, beta-ethylenically unsaturated carboxylic acid having at least about 3% of the carboxylic acid groups neutralized.
A golf ball comprising:
A golf ball comprising a cover and a core centrally disposed within said cover, wherein at least one of said core and said cover includes a composition blend comprising a polyamide-ionomer graft copolymer and an ionomer.
