Abstract
A method of production of a modified conjugated diene rubber including a first step of polymerizing a monomer containing at least a conjugated diene compound by using a polymerization initiator in an inert solvent so as to obtain a conjugated diene polymer having an active end, and a second step of causing a compound represented by a following formula (1) to react with the active end of the conjugated diene polymer having an active end:wherein, in formula (1), each of R1 to R3 independently is an alkyl group having 1 to 4 carbon atoms, R4 is a hydrocarbon group containing an aromatic ring and having 6 to 10 carbon atoms, R5 is an alkyl group having 1 to 6 carbon atoms, and “n” is an integer of 0 to 10.
