Japanese Patent JP6196982
Kind Code:
B2
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 a sulfone, a sulfoxide, and a phosphine oxide; and (ii) polymerizing conjugated diene monomer in the presence of the active catalyst and a polymerization modulator selected from the group consisting of a sulfone, a sulfoxide, and a phosphine oxide.
