<P>PROBLEM TO BE SOLVED: To provide a method for producing a conjugated dienic polymer, capable of providing a polymer composition excellent in fuel consumption saving. <P>SOLUTION: The method for producing a conjugated dienic polymer includes: adding the following compounds (I) and (II) as polymerization initiator components in this order to a solution containing at least one monomer component in a hydrocarbon as a solvent; and polymerizing the monomer component containing a conjugated diene compound and a silicon-containing vinyl compound. (I): an organic alkaline metal compound. (II): a compound represented by formula (1), wherein R<SP POS="POST">11</SP>is a 3-20C hydrocarbylene group which may have, as a heteroatom, at least one atom selected from the atom group consisting of a silicon atom, a nitrogen atom and an oxygen atom. <P>COPYRIGHT: (C)2013,JPO&INPIT |
