FIELD: chemistry.
SUBSTANCE: invention relates to a method for the preparation of a conjugated diene polymer. Method includes the step of preparing a polymer solution of a conjugated diene comprising a conjugated diene polymer and a solvent, and the step of removing volatile substances by moving the polymer solution of the conjugated diene by means of a device having rotating double augers, the volatile components of the solvent being removed at a certain ratio of the auger motor current at the volatile matter removal step and the auger motor current value in the absence of load.
EFFECT: invention makes it possible to improve the efficiency of removing volatile substances by suppressing gel formation.
