DIIMINE METAL COMPLEX, METHOD FOR PRODUCTION THEREOF AND USE THEREOF Russian patent published in 2025 - IPC C07F15/04 C07F15/00 C08F4/70 C08F10/02 C08F110/02 

FIELD: chemistry.

SUBSTANCE: present invention relates to a diimine metal complex represented by formula I. In formula I, the values of radicals are as follows: R₁ and/or R₂ represent(s) a group described by formula A, in which R¹-R⁵, each independently selected from a group consisting of a hydrogen atom, a halogen, a hydroxy group, C1-C20-alkyl with or without a substituent Q, C2-C20-alkenyl with or without a substituent Q, C2-C20-alkynyl with or without substitute Q, C1-C20-alkoxy group with or without substitute Q, C2-C20-alkenoxy group with or without substitute Q, C2-C20-alkinoxy group with substitute Q or without it, C6-C20-aryl with or without substitute Q, C6-C20-aryloxy group with or without substitute Q, C7-C20-arylalkyl with substitute Q or without it, C7-C20-arylalkoxy group with substitute Q or without it, C7-C20-alkylaryl with or without a substitute Q and a C7-C20-alkylaryloxy group with or without a substitute Q, and R¹-R⁵ are optionally combined to form a ring or a cyclic system; R₃ and R₄ are each independently selected from a group consisting of a hydrogen atom, a halogen, a hydroxy group, a C1-C20 hydrocarbon group with or without a substituent Q, and adjacent groups R₃ and R₄ are optionally combined to form a ring or cyclic systems; each R₁₁ independently represents a C1-C20 hydrocarbon group with or without a substituent Q; each Y independently represents an atom of a non-metallic element of Group VIA; each M is independently a Group VIII metal; each X independently represents a halogen; substitute Q is selected from a group consisting of halogen, hydroxy group, C1-C10-alkyl, halogenated C1-C10-alkyl, C1-C10-alkoxy group and halogenated C1-C10-alkoxy group. Also disclosed is a method of producing a metal complex and use thereof in polymerisation of olefins.

EFFECT: disclosed complex is used as a main catalyst in catalysis of polymerisation of olefins and enables to achieve catalytic polymerisation activity at high temperature to obtain branched polyethylene with high molecular weight and narrow molecular weight distribution.
