Abstract:
In general the present invention provides a process for forming conjugated diene polymer, the process comprising the step of polymerizing conjugated diene monomer in the presence of a catalytically effective amount of a catalyst composition formed by combining (a) a nickel-containing compound, (b) an alkylating agent, (c) a fluorine-containing compound, (d) a carboxylic acid, and (e) an alcohol.
