Abstract:
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 amine; and (ii) polymerizing conjugated diene monomer in the presence of the active catalyst and an amine.
