FIELD: chemistry.
SUBSTANCE: system comprises the first and the second reservoirs of the first and the second polymerization catalyst for storing the polymerization catalyst, the first and the second control valves of the first and the second catalyst for controlling the flow of the polymerization catalyst into a polymerization catalyst mixing/collecting vessel, a polymerization catalyst mixing/collecting tank comprising a stirrer located inside the mixing/collecting tank of the polymerization catalyst and configured to mix or dissolve a part or all of the first polymerization catalyst, the second polymerization catalyst, and a solvent to form a polymerization catalyst solution, a heating system connected to the polymerization catalyst mixing and collecting tank and configured to maintain the temperature of the polymerization catalyst solution above a predetermined threshold, a pre-contact reactor configured to receive feed streams, containing an activator and a polymerization catalyst solution from the mixing/collecting tank of the polymerization reactor to form a catalytic complex, and a conduit configured to transfer the catalytic complex from the outlet of the pre-contact reactor to the reactor.
EFFECT: efficient production of the catalyst solution, reducing the transportation costs of the catalyst solution.
