Abstract
Disclosed herein is a golf ball and method for making the same. The golf ball has an ionomeric cover which includes a high melt ionomer having a Vicat softening temperature of 74° C. or more (preferably 80° C. or more, more preferably, 84° C. or more) and a melt temperature of 96° C. or more (preferably 98° C. or more, and most preferably 100° C. or more). Additionally, the high melt ionomer utilized in the invention exhibits a difference in melt temperature and Vicat temperature of 25° C. or less (preferably 19° C. or less, more preferably, 17° C. or less). The golf ball cover is superior in heat resistance to a conventional cover but is otherwise substantially identical in composition.
