Abstract

The present invention is directed to improved polybutadiene compositions suitable for use in molded golf ball core construction. The improved polybutadiene compositions are composed of at least two certain types of polybutadiene, which has the effect of increasing the resiliency of the resulting molded cores and greatly facilitates processing of the compositions and forming the cores. Also disclosed are improved golf ball cores (20, 60), and balls (10, 50) utilizing such cores (20, 60), formed from particular ultra high Mooney viscosity polybutadiene.
