Abstract
A process for preparing a polydiene, the process comprising the step of polymerizing conjugated diene monomer with a lanthanide-based catalyst system including the combination or reaction product of: (a) a lanthanide compound selected from the group consisting of lanthanide organophosphates, lanthanide organophosphonates, and lanthanide organophosphinates, (b) an alkylating agent, and (c) a chlorine-containing compound, where said step of polymerizing takes place within a polymerization mixture that includes less than 20% by weight of solvent based on the total weight of the polymerization mixture.
