CATALYST COMPONENT, OLEFIN POLYMERIZATION CATALYST (VARIANTS) AND METHOD OF POLYMERIZATION OF OLEFINS Russian patent published in 2000 - IPC

FIELD: chemistry of polymers. SUBSTANCE: described is solid olefin polymerization catalyst component comprising magnesium halide in active form, titanium compound comprising at least one Ti halide bond, and electron- donor compound applied on said catalyst component. Electron-donor compound is selected from cyclopolyene 1,3-diether compound of formula I: wherein R, the same or different, are hydrogen, halogen or linear or branched C_1-20 radicals; R¹ radicals, the same or different, are selected from group consisting of hydrogen, halogen or linear or branched C_1-20 radicals; R¹¹ radicals, the same or different, are selected from group consisting of hydrogen, halogen or linear or branched C_1-20 radicals. Also described are olefin polymerization catalyst (variants) and method of polymerization. EFFECT: high activity and stereospecificity of the catalyst during polymerization of olefins. 17 cl, 7 ex
