FIELD: chemistry.SUBSTANCE: invention relates to the technical field of olefin polymerisation, in particular to an olefin polymerisation apparatus and to a method of polymerising olefins for producing polyolefins. Device includes reactor-polymeriser for homopolymerisation and/or copolymerisation of olefins, condensation unit for condensation of gaseous material leaving reactor-polymeriser, gas and liquid separation unit for separation of gas and liquid on material from condensing unit, to produce gas and condensate, storage tanks for receiving condensate coming from gas and liquid separation unit, and control unit, under which gas from gas and liquid separation unit is supplied to reactor-polymeriser and condensate from accumulating tanks is selectively supplied to reactor-polymeriser to achieve switching between gyopolymerisation and copolymerisation of olefins in reactor-polymeriser.EFFECT: invention enables to obtain polyolefin products, having excellent mechanical properties and excellent processability and having a wide field of application and high application value.23 cl, 3 dwg, 7 ex |
