<p><P>PROBLEM TO BE SOLVED: To provide a golf ball material overcoming the poor durability that is characteristic of polyamide-containing materials, having a good durability and scuff resistance, having an excellent thermal stability, flow and processability, and possessing a suitable hardness. <P>SOLUTION: The invention provides golf ball materials which include, in admixture, (A) an oxygen-containing inorganic metal compound, (B) one or more polymers selected from the group consisting of multi-component polyamides, and (C) an acid-containing polymer, and additionally includes, if the oxygen-containing inorganic metal compound (A) does not include a zinc cationic species, (D) a zinc ionomer which includes at least a zinc cationic species, and also provides methods for preparing such golf ball materials. The golf ball materials are multi-component polyamide blend compositions having an excellent flow and processability and a suitable hardness, making them ideal as materials for obtaining high-performance golf balls which are endowed with outstanding durability and scuff resistance without any loss in rebound resilience. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
