Abstract

Official abstract text for this publication.

The present invention provides resin compositions for golf balls which have excellent flexibility, fluidity, and resilience, and golf balls formed from the resin compositions. The present invention relates to a resin composition for golf balls including a polymer that contains a diene polymer moiety and a carboxylic acid-based moiety wherein carboxyl groups derived from the carboxylic acid-based moiety are neutralized.

First claim

Opening claim text (preview).

1 . A resin composition for golf balls, comprising a polymer that contains a diene polymer moiety and a carboxylic acid-based moiety wherein carboxyl groups derived from the carboxylic acid-based moiety are neutralized, wherein the polymer is obtained by neutralizing carboxyl groups and (anhydrous) dicarboxyl groups contained in a reaction product of a diol compound and a diene polymer containing an (anhydrous) dicarboxylic acid grafted thereon. 2 . The resin composition for golf balls according to claim 1 , wherein the diol compound is at least one selected from the group consisting of C 2 -C 20 hydrocarbons having two hydroxy groups, C 2 -C 20 hydrocarbons having two hydroxy groups and at least one ether bond, C 2 -C 20 hydrocarbons having two hydroxy groups and 1 to 3 carboxyl groups, and high molecular weight hydrocarbons having two hydroxy groups. 3 . The resin composition for golf balls according to claim 1 , wherein the reaction product contains 4 to 50% by mass of carboxyl groups and (anhydrous) dicarboxyl groups, and the polymer has a degree of neutralization of the carboxyl groups and (anhydrous) dicarboxyl groups of 20 to 300%. 4 . The resin composition for golf balls according to claim 1 , wherein the carboxyl groups are neutralized with at least one metal ion selected from the group consisting of Na + , Mg 2+ , Ca 2+ , and Zn 2+ . 5 . A golf ball, formed from the resin composition for golf balls according to claim 1 .
