FIELD: chemistry.
SUBSTANCE: present invention discloses a catalyst component for the polymerisation of olefins, comprising the reaction products of the following components: (1) solid component; (2) at least one titanium compound; and (3) at least two internal electron donors; where the solid component contains a magnesium compound represented by formula (1) and an epoxide represented by formula (2), where RI is a linear or branched C1-C12 alkyl; RII and RIII are the same or different and independently represent hydrogen or unsubstituted or halogen-substituted linear or branched C1-C5 alkyl; X is halogen; m is in the range from 0.1 to 1.9, n is in the range from 0.1 to 1.9 and m + n = 2, where the solid component is obtained by reacting a solution of an alcohol adduct of a magnesium halide, containing a polymer stabiliser of a disperse system, with an epoxide of formula (2), wherein the content of the epoxide of formula (2) is in the range from 0.01 to 0.8 mol per mol of the magnesium compound of formula (1). Method of producing a catalyst component, a catalyst component, an olefin polymerisation catalyst, and an olefin polymerisation method are also disclosed.
(1) 
(2).
EFFECT: technical result consists in obtaining a catalyst component, which exhibits a higher catalytic activity, a higher stereo-directing capacity, improved sensitivity to hydrogen, and its use in the catalyst in the polymerisation of olefins allows to obtain polymers with high stereoregularity, having a high melt index and a low content of polymer fines.
