FIELD: chemistry.

SUBSTANCE: invention relates to a catalyst composition for the dimerization of ethylene, comprising: titanate of the formula Ti(OR)₄, where R is the same or different and each R is a hydrocarbon residue, where the hydrocarbon residue is an alkyl group or an aryl group; a catalytic additive, wherein the catalytic additive is a simple dibutyl ether, an aromatic ether of the formula R¹OR², where R¹ and R² are the same or different and each is a substituted or unsubstituted C_6-15 aromatic group, or a combination thereof; a catalyst modifier, where the catalyst modifier is an amine catalyst modifier or an additional ether catalyst modifier, which differs from the dibutyl ether and aromatic ether, where the catalyst additive and the further catalyst modifier are present in a molar ratio of about 1:5 to about 5:1, and an organoaluminum compound. The invention also relates to a method of producing a catalyst composition, a method of producing an alpha-olefin, and a method of producing a product for further processing thereof.

EFFECT: improved output and activation time.
