A method for the preparation of polymer on the basis of a conjugated diene and a process for the preparation of a polymer composition on the basis of a conjugated diene

摘要

The present invention relates to a process for producing a polymer based on a conjugated diene, comprising polymerizing monomers, which is a conjugated diene compound, a compound represented by the following formula (1) and a compound represented by the following formula (2) using an organoalkali metal compound is and a secondary amine compound, and then reacting a compound with a nitrogen atom and / or a silicon atom with an active end of the polymer formed by the polymerization, E¹-A¹ (1)where e¹ a hydrocarbon radical having a polymerizable carbon-carbon double bond and a¹ a substituted amino group or a nitrogen-containing heterocyclic radical, E²-A² (2)where e² a hydrocarbon radical having a polymerizable carbon-carbon double bond and a² represents a substituted silyl group.
