is a linking group that links the amine and salt functional groups and is aliphatic, alicyclic, arylaliphatic or aromatic, X is an anionic group, M is a positively charged species, a is 1-4, m is 0 or greater, n is 1-4, o is 1-4 and p is 0-4, more typically 1-4. An amount of the amine compound is used to react with at least a portion of the reactive functional groups. A method for making a golf ball also is disclosed, as are golf balls comprising disclosed ionomers. At least one component of a golf ball, such as a cover layer, is made comprising disclosed ionomers. The golf ball can have any construction suitable for a golf ball, including multi-layered balls, such as a 3- or 4-piece ball.
本发明公开了离子聚合物反应产物,其通过将至少具有一个反应性羧基和/或异氰酸酯基或等效的功能基团或由其衍生的单体、低聚物或聚合物与一种同时具有胺基和阴离子功能基团的胺化合物结合而制成,其具有以下化学式[RHN—(R1)m—(X−)n]o-Ma+p,其中R为氢、脂肪、脂环、芳基脂肪或芳香族,R1是连接胺基和盐基团的连接基团,为脂肪、脂环、芳基脂肪或芳香族,X为阴离子基团,M为正电荷物种,a为1-4,m为0或更大,n为1-4,o为1-4,p为0-4,更通常为1-4。使用一定量的胺化合物来与至少部分反应性功能基团反应。本发明还公开了一种制造高尔夫球的方法,以及包括所述离子聚合物的高尔夫球。高尔夫球的至少一个组件,如覆盖层,是由所述离子聚合物制成的。高尔夫球可以具有适合高尔夫球的任何结构,包括多层球,如3或4层球。
