Provided is a method for producing conjugated diene rubber, comprising: a first step in which, in an inert solvent, a monomer containing a conjugated diene compound is polymerized using a polymerization initiator, to obtain a conjugated diene polymer having an active terminal; a second step in which siloxane is reacted with the conjugated diene polymer chain having an active terminal; and a third step in which the conjugated diene polymer chain reacted with siloxane obtained in the second step is reacted with a compound represented by general formula (1). (In general formula (1), X1 represents a functional group selected from a hydrocarbyloxy group, a halogen group and a hydroxyl group, R1 represents a hydrocarbon group which may have a substituent, R2 and R3 independently represent hydrocarbon groups which may have a substituent, R2 and R3 may be bonded to one another to form a ring structure with the nitrogen atoms bonded thereto, and if forming said ring structure, in addition to the nitrogen atoms to which these are bonded, it is also possible to form a ring structure together with hetero atoms other than the nitrogen atoms to which these are bonded. r is an integer from 0-2.) |
