| abstract |
The present invention provides a method for producing a conjugated diene rubber, comprising a 1 st step, a 2 nd step, and a 3 rd step, wherein the 1 st step is a step of polymerizing a monomer containing a conjugated diene compound in an inert solvent using a polymerization initiator to obtain a conjugated diene polymer chain having an active end; a 2 nd step of adding an organosiloxane represented by the following general formula (1) to the conjugated diene polymer chain having an active end in a proportion of 1 mol or more in terms of the number of repeating units having a siloxane structure (-Si-O-) in the organosiloxane, based on 1 mol of the polymerization initiator used in the 1 st step; the 3 rd step is a step of reacting a compound represented by the following general formula (2) with the organosiloxane-reacted conjugated diene polymer chain obtained in the 2 nd step. |
