Abstract:
A process for preparing a polydiene, the process comprising the steps of: polymerizing conjugated diene monomer with a metallocene complex catalyst system within a polymerization mixture that includes less than 20% by weight of solvent based on the total weight of the polymerization mixture, where the metallocene complex catalyst system includes the combination or reaction product of: (a) metallocene complex, (b) an alkylating agent, and optionally (c) a non-coordinating anion.
