CATALYST COMPONENT FOR POLYMERIZATION OF ETHYLENE IN HIGH-LINEAR POLYETHYLENE, A CATALYST AND A METHOD FOR PREPARING IT Russian patent published in 2019 - IPC C08F4/70 C08F4/602 C07F15/06 C08F110/02 

FIELD: chemistry.

SUBSTANCE: invention relates to the catalyst component for the ethylene polymerization, to the catalyst, and to the catalyst production method. Catalyst component has a structure represented by general formula 1, where substituents R¹ and R² independently selected from a group comprising a hydrogen atom and alkyls; and the cycloalkyl substituent is selected from the group consisting of cyclopentyl, cyclohexyl, cycloheptyl, cyclooctyl, cyclononyl, cyclodecyl, and cyclododecyl (i.e., g = 1, 2, 3, 4, 5, 6, 8). Catalyst for polymerization of ethylene to obtain high-linear polyethylene includes at least one compound of general formula 1; at least one organoaluminium activator, optionally ethylene and at least one hydrocarbon solvent. Method of preparing catalyst includes mixing in any sequence of suspension or solution of at least one compound of general formula 1, suspension or solution of at least one organo-aluminum activator optionally in presence of ethylene in the medium of at least one hydrocarbon solvent.

EFFECT: obtaining catalyst component not described before for production of high-linear polyethylene with MM of 6,41–25,96 kg/mol and catalyst containing this component.
