FIELD: chemistry.
SUBSTANCE: polymerisation of polyolefin, which is carried out by bringing into contact in the reactor an olefin monomer and optionally a comonomer with a catalyst system in the presence of induced condensing agents (ICA) and optionally hydrogen. ICA can contain two or more ICA components. Change in relative concentration of two or more components of ICA is carried out in accordance with equivalence factors of ICA, which enable to increase rate of production of polyolefin while maintaining temperature of adhesion, increase rate of production of polyolefin with increase in temperature drop of dew point ICA.
EFFECT: ICA composition influences rate of polyolefin production.
