TRANSITION METAL COMPOUND FOR AN OLEFIN POLYMERIZATION CATALYST AND AN OLEFIN POLYMERIZATION CATALYST CONTAINING A TRANSITION METAL COMPOUND Russian patent published in 2021 - IPC C08F4/6592 C08F4/649 C08F4/642 C08F4/52 

FIELD: chemical industry.

SUBSTANCE: invention relates to transition metal compounds represented by the chemical formula 1, where M is any metal made of zirconium (Zr) and hafnium (Hf); group Q, each independently, is a C_1-20-alkylamido group; X is a nitrogen atom (N); substituents R₁, R₂, R₃, R₄, R₅, R₆, R₇, R₈, R₉, R₁₀ and R₁₁, each independently, are a hydrogen atom; substituents R₁₂ and R₁₃ are connected to each other with the formation of an unsubstituted C_4-20-ring. The invention also relates to an olefin polymerization catalyst containing a transition metal compound represented by the chemical formula 1.

EFFECT: development of a catalyst having a higher activity and a higher copolymerization ability at a high temperature of 100°C or higher and being cost-effective.
