FIELD: technological processes.
SUBSTANCE: invention relates to a method of producing a low-molecular alpha-olefin polymer, comprising a production step and a step of completing the operation, in which at the operation completion stage, the feed liquid supply position to the distillation column is changed to a position lower than the feed liquid supply position to the distillation column at the production stage.
EFFECT: suppressing deposition of polymers dissolved in a solvent in high concentration at the stage of completion of operation, as well as suppression of plugging of the device with polymers, even when polymers with high concentration are deposited.
