Abstract:
A golf ball comprising:a core formed from a composition comprising: a resilient polymer component of at least one polybutadiene having a high molecular weight average and a 1,4-cis content of greater than about 50 weight percent; a free-radical initiator; and an amount of reinforcing polymer component having a sufficiently low viscosity at a mixing temperature to facilitate mixing of the reinforcing polymer component with the resilient polymer component and having a crystalline melting point sufficiently low to facilitate the mixing while avoiding substantial crosslinking, wherein the uncrosslinked composition has a flexural modulus of greater than about 3.5 Mpa; and a cover formed from a composition comprising at least one ionomer or at least one urethane.
