FIELD: chemistry.
SUBSTANCE: present invention relates to a catalytic component for polymerisation of olefin CH2=CHR, in which R is hydrogen or C1-C12 alkyl or aryl group, containing magnesium, titanium, halogen and an electron-donor compound (a), which is at least one compound, chosen from a group consisting of esters of dibasic compounds of formula (I). The catalytic component can optionally contain an electron-donor compound (b), chosen from a group consisting of esters of aliphatic and aromatic carboxylic acids, and/or an electron-donor compound (c), chosen from a group consisting of derivatives of 1,3-diester of formula (IV). Formula (I) is of the form: 
in which R1, R' and A are described in the description. The invention also pertains to a polymerisation catalyst and method of polymerising olefin. All aspects of the invention include the catalytic component described above.
EFFECT: wide assortment of obtained polymers; the polymers have wide molecular mass distribution.
