Abstract
In a golf ball comprising a core and a cover of one or more layers, at least one layer of the cover is formed primarily of a mixture comprising (A) an ionomer resin, (B) a thermoplastic elastomer and (C) a thermoplastic block copolymer terminated with a functional group capable of reacting with the ionomer resin, in such a proportion as to provide a A/(B+C) weight ratio between 50/50 and 98/2 and a B/C weight ratio between 9/1 and 1/1. The golf ball has improved rebound, a soft feel upon impact, good durability and good moldability.
