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 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.

摘要： A process for preparing a blend of cis-1,4-polybutadiene and syndiotactic 1,2 polybutadiene, the process comprising the steps of (i) polymerizing 1,3-butadiene in the presence of a lanthanide-based catalyst to form a polymerization mixture including cis-1,4-polybutadiene, and (ii) polymerizing 1,3-butadiene in the presence of a cobalt-based catalyst within the polymerization mixture including cis-1,4-polybutadiene to form syndiotactic 1,2-polybutadiene and thereby produce a blend of cis-1,4-polybutadiene and syndiotactic 1,2-polybutadiene.
