FIELD: polyethylene production.
SUBSTANCE: present invention relates to a method for the production of a multimodal polyethylene composition in a reactor system, a multimodal polyethylene composition obtained by this method, as well as a container made of it. The reactor system includes the first reactor, a hydrogen removal plant arranged between the first reactor and the second reactor and including at least one tank connected to equipment for pressure relief that makes it possible to bring the working pressure to the pressure in the range from 100-200 kPa (abs.), the second reactor, and the third reactor.
EFFECT: increase in mechanical properties of polyethylene compositions.
