ABSTRACT:
The present invention is directed to improved polybutadiene compositions suitable for molded golf ball core construction. The improved polybutadiene compositions contain specific naturally occurring, essentially non-reinforcing, crystalline (preferably microcrystalline) silica particles which have the effect of increasing the resilience and/or hardness of the resulting molded cores. In addition, the present invention is also directed to golf balls produced utilizing the improved core compositions.
