FIELD: chemistry.
SUBSTANCE: present invention relates to components of a catalyst for polymerisation of olefins, catalysts obtained from said components, and use thereof in methods of polymerisation of olefins. Catalyst component contains Mg, Ti and an electron donor compound of formula (I), wherein R1-R3, identical or different from each other, represent hydrogen, C1-C15-hydrocarbon groups, optionally containing a heteroatom, selected from halogen, P, S, N and Si, group R5 is selected from phenyl groups, mono- or polysubstituted with halogens, groups R4 and R6 are selected from C1-C10-alkyl groups, wherein said groups R1-R4 can also optionally bind to form a saturated or unsaturated mono- or polycycle.
EFFECT: catalysts demonstrate excellent balance of high stereoselectivity and high activity.
