FIELD: chemistry.
SUBSTANCE: invention relates to polymerisation of olefins. Described is a method of polymerising at least one olefin monomer in more than one polymerisation zone of one or more polymerisation reactors using a highly active catalyst, which is fed into the front end of the reactor to form solid polymer particles. The method is carried out in the apparatus.
EFFECT: wider molecular weight distribution of the obtained polymer.
