| 摘要 |
A method of producing a conjugated diene polymer comprising polymerizing monomers comprising at least one conjugated diene hydrocarbon under solution polymerization conditions such that substantially all of said monomers are polymerized, terminating the thus formed polymer to deactivate substantially all of the active polymer lithium, and then polymerizing additional portions of said monomers in solution with at least a portion of the terminated polymer under conditions such that substantially all of said additional monomers are polymerized.
