FIELD: chemistry. n SUBSTANCE: invention relates to the method for producing a solid organomagnesium precursor having the formula {Mg(OR')X}.a{MgX 2 }.b{Mg(OR') 2 }.c{R'OH}, where R' is selected from the hydrocarbon group, X is selected from the halide group, and a:b:c is in the range of 0.01-0.5:0.01-0.5:0.01-5. The method comprises the magnesium source contact with a solvating agent, an organohalide and an alcohol with obtaining a solid organomagnesium precursor. The solvating agent is selected from the group consisting of dimethyl ether, diethyl ether, dipropyl ether, diisopropyl ether, ethyl methyl ether, n-butyl ether, n-butyl ethyl ether, di-n-butyl ether, di-isobutyl ether, isbutyl methyl ether, isobutyl ethyl ether, dioxane, tetrahydrofuran, 2-methyltetrahydrofurane, tetrahydropyrane, and combinations thereof. The solid organomagnesium precursor, the method for obtaining the catalyst composition, the catalyst composition, the method for obtaining the catalyst system, the catalyst system and method for the polymerization and / or copolymerization of olefins are proposed as well. n EFFECT: invention allows to simplify the method of obtaining the organomagnesium precursor which is used in manufacturing the catalyst for the polymerization of olefins, having high activity. n 43 cl, 1 dwg, 3 tbl, 3 ex |
