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.
在一种高尔夫球中,包括一个球芯和一层或多层外层,其中至少有一层外层主要由混合物形成,混合物包括(A)离子聚合物
树脂、(B)热塑性弹性体和(C)热塑性嵌段共聚物,嵌段共聚物的末端带有能与离子聚合物
树脂反应的官能团,其比例为 A/(B+C) 重量比介于 50/50 和 98/2 之间,B/C 重量比介于 9/1 和 1/1 之间。这种高尔夫球的回弹性更好,击球时手感柔软,耐久性好,成型性好。
