FIELD: chemistry.
SUBSTANCE: invention relates to catalytic chemistry. Disclosed is a catalyst composition for polymerisation α-olefins, containing boron trifluoride and at least one proton cocatalyst; where the proton cocatalyst has the structural formula: X-(CH2)n-OH, where n is integer from 1 to 10; X is selected from nitro, halogen, cyano, sulphonic acid group, aldehyde group, acyl group, carboxyl and amino. Also disclosed are method of producing a catalyst composition and use of the catalyst composition.
EFFECT: providing a catalyst system for stereospecific polymerisation α-olefins with high selectivity with respect to the target product.
