FIELD: oil and gas industry.
SUBSTANCE: method contains the olefin polymerisation, producing the olefin-based polymer in the polymerisation reactor and light stabiliser, based on the hindered amine adding into the polymerisation reactor. The polymerisation reactor includes the carryover zone and the catalyst supply system for supplying the catalyst system. The method also includes monitoring of the electrostatic activity level in the carryover zone and controlling the light stabiliser amount, based on the hindered amine, added into the polymerisation reactor, based on the electrostatic activity level in the carryover zone.
EFFECT: control of the static charge level in the reactor, preventing, reducing the plate formation or its dissolution, reducing the plates formation or its dissolution, preventing the polymer flashes and discontinuity formation, resulting in the static charges excessive levels.
