The invention relates to a method of manufacturing conjugated diene-based polymers. The conjugated diene-based polymers are obtained by polymerizing conjugated diene monomers or conjugated diene monomers and vinyl aromatic monomers using an initiator, wherein the initiator is obtained by reacting a divinylarene-like compound represented by the formula (1) with an organic alkali metal; A and B are CnH2n+1 or an aromatic ring, n is 0~5, A and B can be the same or different, and Q is an aromatic ring; wherein the molar ratio of the divinylarene-like compound to the effective active organic alkali metal is 1.3-5.0. The present invention further relates to a rubber comprising the conjugated diene-based polymers, and a tire comprising the rubber.
