Abstract
The present invention provides a process for producing a conjugated diene-based polymer, comprising polymerizing a monomer component containing a conjugated diene compound and a silicon-containing vinyl compound using a polymerization initiator represented by the following formula (1)wherein, R11 represents a hydrocarbylene group having 6 to 100 carbon atoms, R12 and R13 represent a hydrocarbyl group optionally having a substituent, or a trihydrocarbylsilyl group, or R12 and R13 are bonded to represent a hydrocarbylene group optionally having, as a hetero atom, at least one kind atom selected from the atomic group consisting of a silicon atom, a nitrogen atom and an oxygen atom.
