Beschreibung
Zusammenfassung:	FIELD: polymerization catalysts. ^ SUBSTANCE: invention relates to novel organometallic compounds and to olefin polymerization catalytic systems including such organometallic compounds, and also to a method for polymerization of olefins conduct in presence of said catalytic system. Novel organometallic compound is prepared by bringing into contact (i) compound of general formula I: (I), where Ra, Rb, Rc, and Rd, identical or different, represent hydrocarbon groups; and (ii) Lewis acid of general formula MtR13, where Mt represents boron atom and R1, identical or different, are selected from halogen and halogenated C6-C30-aryl groups. ^ EFFECT: enabled preparation of novel olefin polymerization cocatalysts, which reduce use of excess cocatalyst relative to alkylalumoxanes, do not lead to undesired by-products after activation of metallocene, and form stable catalytic compositions. ^ 14 cl, 1 tbl, 32 ex
