FIELD: chemistry.
SUBSTANCE: invention relates to a gas-phase polymerisation method for producing polyolefins. Described is a method which involves reaction of monomers, a catalyst system and an inert condensate reagent, which contains most part of propane, under gas-phase conditions of polymerisation in condensation mode to obtain polyolefin. Inert condensing reagent additionally contains inert condensing reagent C4-C8. Ratio of the number of moles of propane to the amount of moles of the inert condensing reagent C4-C8 is greater than or equal to 65:35.
EFFECT: technical result is high efficiency when producing products while maintaining continuous operation of the reactor system when carrying out the method in continuous mode, as well as wider range of polymers having different characteristics, with higher efficiency.
