GOLF BALL WITH SOFT CORE

摘要

The present invention is directed to a golf ball (10) comprising a core (20) and cover (30). The core (20) includes a first polybutadiene rubber obtained utilizing a cobalt catalyst and having a Mooney viscosity in the range of 70 to 83. The second polybutadiene rubber is obtained utilizing a neodynium series catalyst and having a Mooney viscosity from 30 to 70. The cover (30) includes at least one sodium ionomer and one zinc ionomer.
