The first step of obtaining a conjugated diene-based polymer chain having an active end by polymerizing a monomer containing a conjugated diene compound and a vinyl compound containing a functional group capable of interacting with silica in an inert solvent, using a polymerization initiator, and , A second step of reacting a siloxane compound to the active end of the conjugated diene polymer chain having the active end, and a conjugated diene polymer chain obtained by reacting the siloxane compound obtained in the second step, a hydrocarbyloxysilane compound It provides a method for producing a conjugated diene-based rubber comprising a third step of reacting. |
