FIELD: polymerization reactor system.
SUBSTANCE: invention relates to a polymerization reactor system and its operation. The polymerization reactor system comprises a reactor for contacting the catalyst system with an olefin monomer and optionally an olefin comonomer under polymerization reaction conditions to form an olefin polymer; a catalyst preparation vessel for bringing into contact a first transition metal compound, a second transition metal compound, an activator, and optionally a co-catalyst to form a catalyst system; and an analytical system for determining the concentration of the first transition metal compound in the solution containing the first transition metal compound and the second transition metal compound present in the polymerization reactor system.
EFFECT: improvement of methods for obtaining a multicomponent catalytic system.
