Document Type and Number:
Japanese Patent JP2013540862
Kind Code:
A
Abstract:
A method for producing a polydiene, the method comprising of combining a lanthanide compound, an alkylating agent, a halogen source, and optionally conjugated diene monomer to form an active preformed catalyst; independent of step (i), introducing an amine with conjugated diene monomer to be polymerized; independent of step (i), introducing the active preformed catalyst to the conjugated diene monomer to be polymerized to form an active polymerization mixture, where the active polymerization mixture includes less than 10% by weight, based on the total weight of the active polymerization mixture, of a solvent; and allowing the monomer to be polymerized to polymerize in the presence of the amine.
