摘要： A golf ball including a core, and a gamma irradiated, ionomeric, dimpled cover having a Shore D hardness of 55 or less as measured on a non-dimpled portion of the cover, the dimples maintaining their shape when the cover is subjected to heat treatment at 160.degree.-180.degree. F. for at least one hour. In making the golf ball, the dimpled cover is subjected to gamma irradiation in a dosage sufficient to increase the vicat softening point in degrees Fahrenheit of the cover by at least 2.5%.

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.

摘要： Disclosed herein is a golf ball with a cover formed from a polyamide composition and a method of making the same. More specifically, the golf ball has a cover which contains a combination of a polyamide component and an ionomeric component or a non-ionomeric terpolymer component. The cover composition has excellent durability and resistance to cracking, even at cold temperatures. The nylon-ionomer blend is a useful substitute for an ionomer golf ball cover, particularly when a low spin golf ball is desired.

摘要： The present invention is directed to golf ball cover compositions containing metal cation neutralized carboxylic acid based copolymers and/or alkali metal cation neutralized ethylene copolymers such as ethylene alkyl acrylates. Golf balls produced with the cover molded thereon exhibit desired properties of distance and high coefficient of restitution without substantially sacrificing and/or improving characteristics like playability and durability when compared to existing ionomeric resin covers.
