NEW COMPOUND OF TRANSITION METAL BASED ON INDENE, CATALYTIC COMPOSITION BASED ON TRANSITION METAL, CONTAINING SPECIFIED COMPOUND, AND METHOD FOR PRODUCTION OF ETHYLENE HOMOPOLYMER OR COPOLYMER OF ETHYLENE AND α-OLEFIN, USING SPECIFIED COMPOSITION Russian patent published in 2022 - IPC C07F7/28 C07F7/10 C08F10/02 C08F210/16 C08F4/646 C08F4/659 C08F4/6592 

FIELD: chemistry.

SUBSTANCE: invention relates to a complex of transition metal, represented by the chemical formula 1. In the chemical formula 1: M is transition metal of the 4^th group of the periodic table; R₁ is (C1-C20)alkyl; Ar₁ is (C6-C30)aryl, in which aryl in Ar₁ may be additionally substituted with (C1-C20)alkyl; groups from R₂ to R₅ are hydrogen; R₉ is (C1-C20)alkyl; R₆ and R₇ are independently (C1-C20)alkyl, or R₆ and R₇ are bound to each other with formation of a ring; R₈ is hydrogen; X₁ and X₂ are independently (C1-C20)alkyl. A catalytic composition, a method for the production of ethylene homopolymer or copolymer of ethylene and α-olefin, a polymerization method, and an intermediate compound are also proposed.

EFFECT: proposed new complex of transition metal and a catalytic composition including it have high catalytic activity relatively to the production of ethylene homopolymer or copolymers of ethylene and α-olefins.
