摘要：
A nickel-carbene polymerization catalyst system for preparing high cis polydienes is provided. The catalyst system comprises (a) a nickel N-heterocyclic carbene complex, (b) an organoaluminum compound, (c) a fluorine-containing compound, and (d) optionally, an alcohol. Also provided is a process for producing a polydiene comprising reacting a conjugated diene in the presence of a polymerization catalyst comprising (a) a nickel N-heterocyclic carbene complex, (b) an organoaluminum compound, (c) a fluorine-containing compound, and (d) optionally, an alcohol.
