Golf ball compositions containing the ionomer derivatives and acidic copolymer of highly crystalline

摘要

(57) [Abstract] The present invention contemplates a golf ball, the core cover, and a one or more intermediate layers in some cases, the intermediate layer and the cover and / or the golf ball, at least highly formed from the blends and ionomers derivative thereof or a copolymer of crystallinity, including acrylic acid or methacrylic acid of about 35 wt% about 5, copolymers of crystallinity is made from an ethylene / carboxylic acid copolymer to the high degree of In the copolymer, the acid groups of up to about 70% and is polymerized under a pressure ranging from about 20,000psi~ about 50,000psi and a temperature in the range of about 200 ℃ about 130 ℃ ~ are neutralized with metal ions there.
