FIELD: chemistry.
SUBSTANCE: claimed invention relates to solid catalytic component for polymerisation of olefins, including magnesium, titanium, halogen and α-cyanosuccinate compound as internal electron donor, to catalyst, including catalytic component, and to application of catalyst in polymerisation of olefins. Alpha-cyanosuccinate compound I has formula (I):
,
where value of radicals is given in the invention formula. Alternatively, internal electron donor represents combination of α-cyanosuccinate compound I and monofunctional or bifunctional compound E, selected from esters, different from α-cyanosuccinate compound I, ethers, ketones, ketals, amines and silanes.
EFFECT: being applied in polymerisation of propylene, catalyst demonstrates higher catalytic activity and good index of activity by hydrogen, with obtained polymer having high isotacticity and wide distribution of molecular weights.
