To provide a method of manufacturing conjugated diene polymers, rubbers including the conjugated diene polymers, and tires including the rubbers.SOLUTION: The conjugated diene polymers are obtained by polymerizing conjugated diene monomers, or conjugated diene monomers and vinyl aromatic monomers, using an initiator, where the initiator is obtained by reacting a divinylarene-like compound represented by the formula (1) with an organic alkali metal [in the formula, A and B are CnH2n+1 or an aromatic ring, n is from 0 to 5, A and B can be the same or different, and Q is an aromatic ring], and where the molar ratio of the divinylarene-like compound to the effective active organic alkali metal is 1.3-5.0.SELECTED DRAWING: None

    【課題】共役ジエン系重合体の製造方法、共役ジエン系重合体を含むゴム、および該ゴムを含むタイヤを提供する。【解決手段】共役ジエン系重合体は、共役ジエン単量体、または共役ジエン単量体とビニル芳香族単量体とを、開始剤を用いて重合することにより得られる。ここに、開始剤は、式(1)で表されるジビニルアレーン様化合物と有機アルカリ金属とを反応させて得られる。[式中、AおよびBはCnH2n+1または芳香環であり、nは0~5であり、AおよびBは同じであっても異なっていてもよく、Qは芳香環である。]有効活性有機アルカリ金属に対するジビニルアレーン様化合物のモル比は1.3~5.0である。TIFF2023088874000010.tif40155【選択図】なし
