A process for preparing a polydiene, the process comprising the step of polymerizing conjugated diene monomer with a nickel-based catalyst system, where said step of polymerizing takes place within a polymerization mixture that includes less than 20% by weight of organic solvent based on the total weight of the polymerization mixture, where the temperature of the polymerization mixture is maintained below 34° C. during said step of polymerizing, and where the conversion of the conjugated diene monomer is maintained below 30%.
