摘要: A method for producing a polydiene, the method comprising the steps of (i) forming an active catalyst by combining a lanthanide-containing compound, an alkylating agent, and a halogen source in the substantial absence of an organosulfide; and (ii) polymerizing conjugated diene monomer in the presence of the active catalyst and an organosulfide.

摘要: 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.
