METAL CHELATES COMPRISING LIGANDS OF 3-ARYL-SUBSTITUTED INDENYL, CATALYST OF OLEFIN POLYMERIZATION AND METHOD OF POLYMERIZATION Russian patent published in 2002 - IPC

FIELD: chelating compound. SUBSTANCE: invention relates to chelates of metals of the formula (I) where M means titanium, zirconium or hafnium in formal oxidation state +2, +3 or +4; R' means phenyl, biphenyl or naphthyl; R^* means hydrogen atom or hydrocarbyl; X means halogen atom or methyl. Invention relates to also catalysts of olefins polymerization reaction comprising these ligands and a method of polymerization of C₂-C₁₀₀₀₀₀-α-olefins, especially ethylene and styrene, using these catalysts. The use of the novel catalyst of olefins polymerization results to high-effective formation of high-molecular polyolefins in the broad range of conditions of polymerization reaction. EFFECT: improved method of polymerization. 7 cl, 1 tbl, 4 ex
