CATALYTIC SYSTEMS CONTAINING LOW-VALENT TITANIUM-ALUMINUM COMPLEXES AND POLYMERS OBTAINED USING SUCH SYSTEMS Russian patent published in 2021 - IPC C08F210/16 C08F4/6592 C07F7/28 

FIELD: chemistry.

SUBSTANCE: invention relates to a method for obtaining a titanium-aluminum complex having the formula (A), while the method includes contact of a semi-metallocene titanium compound having the formula (B) with an alkyl-aluminum compound having the formula Al(R^X)(R^Y)(R^Z) to obtain a mixture containing a titanium-aluminum complex having the formula (A), where: X₁ and X₂ are independently halogen; R¹, R² and R³ are independently С₁-С₁₀-alkyl group; Cp is a substituted or unsubstituted cyclopentadienyl or indenyl group; and R^X, R^Y and R^Z are independently C₁-C₁₀-alkyl group. The invention also relates to a titanium-aluminum complex having the formula (A), a catalytic composition for olefin polymerization, and a method for olefin polymerization.

EFFECT: development of catalytic systems allowing one to obtain polymers with high melt strength and wide molecular-mass distribution.
