Described are golf balls comprising cores or intermediate layers prepared from thermoplastic compositions having coefficients of restitution equal to or greater than 0.83 and PGA compression greater than 100. Also described is a composition comprising or prepared from (a) at least one aliphatic, mono-functional organic acid having from 16 to 20 carbon atoms, wherein the organic acid is unsaturated and linear; (b) an ethylene acid copolymer consisting essentially of copolymerized comonomers of ethylene and from 18 to 24 weight % of copolymerized comonomers of at least one C

α,β ethylenically unsaturated carboxylic acid, based on the total weight of the ethylene acid copolymer, having a melt index from about 200 to about 600 g/10 minutes; wherein the combined acid moieties of (a) and (b) are nominally neutralized to a level from about 120% to about 200%; and optionally (c) filler.
描述了一种高尔夫球,其核心或中间层由热塑性组合物制备而成,其恢复系数大于或等于0.83,PGA压缩大于100。还描述了一种组合物,包括或由以下成分制备而成:(a)至少一种具有16至20个碳原子的脂肪族单官能有机酸,所述有机酸是不饱和的线性酸;(b)乙烯酸共聚物,其本质上由乙烯和18至24重量%的至少一种C3至C8α,β不饱和羧酸的共聚物化共单体组成,基于乙烯酸共聚物的总重量,其熔融指数在约200至约600克/10分钟之间;其中(a)和(b)的酸基合计被名义上中和至约120%至约200%的水平;以及可选的(c)填料。
