<p>A low compression, resilient golf ball (10) having a center (12) and a cover (16), wherein at least a portion of the ball (10) is formed from the conversion reaction of an amount of polybutadiene, a free radical source, and a cis-to-trans catalyst including at least one inorganic sulfide at a sufficient temperature to form a polybutadiene reaction product which includes an amount of trans-polybutadiene greater than the amount of trans-polybutadiene present before the conversion reaction and a cis-to-trans catalyst including at least one inorganic sulfide. The reaction product preferably has a first dynamic stiffness measured at -50 °C that is less than about 130 percent of a second dynamic stiffness measured at 0°C. A multi-layer golf ball (20, 30) having a center (22, 32), at least one intermediate layer (24, 34, 36) disposed concentrically about the center (22, 32), a cover (26, 38), wherein at least a portion of at least one of the center (22, 32), intermediate layer, or both, are made from the reaction product. Also included are methods of forming such golf balls.</p> |
