Abstract

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 C<n>H<2n+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. <img class="EMIRef" id="b0fcce42-52fd-4469-a43d-6a8524d76a55-ia01" />
