Patent ID: 8110635

Claim:
A method for producing a conjugated diene polymer, the method comprising step 1 and step 2 below: step 1: a step of polymerizing a conjugated diene-containing monomer in a hydrocarbon solvent in the presence of an alkali metal catalyst, thus giving a polymer having a catalyst-derived alkali metal at one terminus of a polymer chain comprising a conjugated diene-based monomer unit; and step 2: a step of reacting the polymer obtained in step 1 and a trialkoxysilane compound represented by Formula (A) below. wherein Y and Z independently denote an oxygen atom or a sulfur atom, R 1 , R 2 , and R 3 independently denote an alkyl group having 1 to 4 carbon atoms, m denotes an integer of 1 to 5, and n denotes an integer of 0 to 5.
