Golf ball covers comprising modulus adjusting fillers

摘要

The present invention is directed to a golf ball with a core and a polymeric layer reinforced with fillers. Such layer can be the cover, a portion of the cover, an intermediate layer, a portion of the intermediate layer, or any layer in the golf ball. The fillers are selected to provide efficient increases in flexural modulus as a function of weight percentage of filler in the polymeric layer. A preferred filler is barium sulfate.
