The present invention is directed to a golf ball exhibiting improved heat
resistance features while maintaining desired playability features.
Particularly, the present invention is directed to a golf ball having a
core and a cover disposed about the core, the cover being less than 20
parts by weight of at least one hard ionomer copolymer having a Vicat
softening temperature of at least about 74.degree. C. and at least 80
parts by weight of at least one soft ionomer. Preferably, the soft ionomer
exhibits a Vicat softening temperature of less than about 50.degree. C.
Preferably, the at least one soft ionomer is a terpolymer.
