Abstract:
A method for producing a modified conjugated diene polymer comprising a polymerization step of obtaining a conjugated diene polymer containing a nitrogen atom in a polymer chain and an active end by copolymerizing a conjugated diene compound and a nitrogen atom-containing vinyl compound, or a conjugated diene compound, an aromatic vinyl compound and a nitrogen atom-containing vinyl compound by use of an alkali metal compound and/or an alkaline earth metal compound as a polymerization initiator, and a modification step of reacting a modifier.
