Abstract:
A method for forming a golf ball which comprises:combining (a) a cis-to-trans catalyst comprising at least one inorganic sulfide; (b) a free radical source; and (c) a first resilient polymer component comprising a cis-polybutadiene component present in an amount greater than about 70 percent; converting a portion of the first resilient polymer component to a second resilient polymer component, wherein at least a portion of the cis-polybutadiene component is converted to a trans-polybutadiene component and wherein the polybutadiene in the second resilient polymer component is at least about 10 percent trans-polybutadiene and less than about 7 percent vinyl-polybutadiene; and forming the second resilient polymer component into at least a portion of the golf ball.
