FIELD: chemistry.
SUBSTANCE: method of polymerization of the monomer in the polymerization system is described. It consists of at least one component attached thereto, which is washed with the wash medium, which is supplied to the polymerization system. First, mentioned component is washed with a first washing medium and then with a second washing medium that differs in composition from the first washing medium. First and second flushing mediums are first and second flushing gases. The flushing gas comprising the olefin monomer, is used when the performance of the polymer is higher than 10 T/h.
EFFECT: prevention of polymer accumulation in the reactor connection zone with other systems, prevention of polymerization mixture contact with seals and similar parts.
