FIELD: chemistry.
SUBSTANCE: claimed invention relates to systems of catalysts of polymerisation of CH2=CHR olefins, where R represents alkyl, cycloalkyl or aryl radical, containing 1-12 carbon atoms, and to method of gas-phase ethylene (co)polymerisation. Catalyst contains (A) solid component of catalyst, which contains Ti, Mg, halogen and is characterised by porosity (PF), measured by method of mercury porosimetry and conditioned by pores with radius equal to or smaller than 1 mcm, which constitutes, at least, 0.3 cm3/g, (B) aluminium-alkyl compound and (C) monohalogenated hydrocarbon, in which halogen is bound with secondary carbon atom.
EFFECT: claimed systems of catalysts are characterized by improved activity in polymerisation.
