METALLOCENE COMPLEX OF LANTHANIDE BORON HYDRIDE, CATALYST SYSTEM CONTAINING SAID COMPLEX, POLYMERISATION METHOD USING SAID COMPLEX AND ETHYLENE AND BUTADIENE COPOLYMER OBTAINED USING SAID METHOD Russian patent published in 2011 - IPC C07F17/00 C08F4/52 C08F210/02 C08F236/06 

FIELD: chemistry.

SUBSTANCE: invention relates to a metallocene complex of lanthanide boron hydride of formula B: where Ln denotes said lanthaide with atomic number from 57 to 71 inclusively, where the lanthanide Ln is bonded to one molecule of a ligand consisting of two fluorenyl groups Cp₁ and Cp₂, which are identical or different, which can be substituted or unsubstituted and which are bonded to each other by a bridge P of formula MR₁R₂, in which M is a group IVA element, and R₁ and R₂, identical or different, denote an alkyl group containing 1-20 carbon atoms, where L denotes an alkali metal selected from a group consisting of lithium, sodium and potassium, where N denotes a molecule of a complexing solvent such as ether, where x denotes a whole number or a fraction greater than 0 and where p is equal to 1 or 2. The invention also discloses a method of producing the complex, a catalyst system, a method for copolymerisation of olefins and a copolymer of ethylene and butadiene.

EFFECT: obtaining a metallocene complex which can be used for copolymerisation of olefins.
