FIELD: chemistry.
SUBSTANCE: invention relates a catalyst component for ethylene polymerisation, a method of producing said component, a catalyst and a polymerisation method. The catalyst component includes a reaction product of (1) a magnesium complex, which is a magnesium halide solution in a solvent system; (2) at least one titanium compound of formula Ti(OR)aXb, where R, X, a, b are given in the claim, and (3) at least one organosilicon compound of formula (I), where the values of radicals are given in the claim. The solvent system is a system comprising at least one organic epoxy compound, at least one organoboron compound, at least one alcohol and optionally at least one inert diluent, or a system which includes at least one organic epoxy compound, at least one organophosphorus compound, at least one alcohol and optionally at least one inert diluent.
EFFECT: catalyst component obtained using said method provides excellent efficiency, including high catalytic activity, good hydrogen sensitivity, narrow particle size distribution of the polymer product, low content of the fine (dust-like) fraction and high bulk weight of the polymer product; a compound of formula (I):
