Zusammenfassung:The invention discloses a binary composite regulating system for homopolymerization or copolymerization of conjugated diene anions, the binary composite regulating system comprises a bistetrahydrofuranyl alkane regulator and an alkyl benzene sulfonic acid alkali metal salt regulator, the molar ratio of bistetrahydrofuranyl alkane to an organic lithium initiator is 0.01-6.0, the molar ratio of the alkyl benzene sulfonic acid alkali metal salt to the organic lithium initiator is 0.15-2, the system adopts a binary composite adjusting system of a bipolar group adjusting agent and a salt adjusting agent with alkali metal, the adjusting capability of the system is greater than that of the bipolar group adjusting agent and the salt adjusting agent when the bipolar group adjusting agent and the salt adjusting agent are independently used, and the content of vinyl in poly-conjugated diene can be controlled to be about 20-80%; and along with the change of polymerization temperature, the content change of the 1, 2-struc
