BISPHENOL METAL COMPLEX, METHOD FOR PRODUCTION THEREOF AND USE THEREOF Russian patent published in 2024 - IPC C07F7/00 C07F7/28 C08F4/6592 C08F10/02 C08F110/02 C08F210/16 

FIELD: chemistry.

SUBSTANCE: invention relates to a bisphenol metal complex having a structure represented by formula Ia. In formula Ia: R₁ and R₁', each is independently selected from the group consisting of a hydrogen atom and a substituted or unsubstituted, linear or branched C₁-C₁₀ alkyl; R₃-R₇, R₃'-R₇', each independently selected from a group consisting of a hydrogen atom and a substituted or unsubstituted, linear or branched C₁-C₁₀-alkyl, and any two adjacent groups from R₃-R₇ optionally connected to form a ring, and any two adjacent groups from R₃'-R₇' optionally connected to form a ring; R₈ and R₉ are each independently selected from the group consisting of a hydrogen atom and a substituted or unsubstituted C₁-C₂₀-hydrocarbyl; each R is independently selected from the group consisting of a hydrogen atom and a substituted or unsubstituted C₁-C₂₀-hydrocarbyl; M and M', each independently represents Group 4 metal; each X is independently selected from a group consisting of a hydrocarbyl having from 1 to 20 carbon atoms, a hydride, an amido group, an alkoxide, an alkyl sulphide, an alkyl phosphide, a halide, a diene, amine, phosphine, ether and combinations thereof; and m and n are independently integer from 1 to 4. Term "substituted" means that one or more hydrogen atoms on the group in question are replaced by C₁-C₆-alkyl, phenyl, benzyl, a halogen atom, a heteroatom, C₁-C₆-alkoxy group, or a carbon atom in the main chain is replaced with a heteroatom. Also disclosed are methods of producing said metal complex and use thereof in polymerisation of olefins.

EFFECT: disclosed bisphenol metal complex exhibits high catalytic efficiency and high ability to incorporate a comonomer.
