NEW CYCLOPENTA[B]FLUORENYL COOMPOUND OF TRANSITION METAL, CATALYTIC COMPOSITION CONTAINING IT, AND METHOD FOR PRODUCTION ETHYLENE HOMOPOLYMER OR ETHYLENE AND ALPHA-OLEFIN COPOLYMER AT ITS USE Russian patent published in 2017 - IPC C07F17/00 C08F4/6592 C08F10/02 C08F210/16 C07C13/66 C07C49/537 

FIELD: chemistry.

SUBSTANCE: invention relates to a new transition metal compound based on a cyclopenta[b]fluorenyl group, to a transition metal catalyst composition containing it and having high catalytic activity for production of an ethylene homopolymer or an ethylene and one α-olefin copolymer, to a method for production of an ethylene homopolymer or an ethylene and α-olefin copolymer with its use and to the resulting ethylene homopolymer or an ethylene and α-olefin copolymer. The transition metal compound is represented by chemical formula 1, where the radicals value is indicated in the claims. A catalyst composition for production of an ethylene homopolymer or an ethylene and α-olefin copolimer contains a transition metal compound of chemical formula 1 and a cocatalyst selected from an aluminium compound, a boron compound and a mixture thereof. Also chemical compounds represented by chemical formulas 12 and 13 are claimed. The catalyst composition has excellent chemical activity of copolymerization with other olefins, while maintaining high catalytic activity even at high temperature, due to its excellent thermal stability, which allows to produce high molecular weight polymers in high yield. [Chemical Formula 1] ; [Chemical Formula 12] ; [Chemical Formula 13] .

EFFECT: claimed compounds can be easily obtained in a high yield.
