CATALYST OF OLEFIN POLYMERIZATION AS AZABOROLINYL METAL COMPLEXES AND METHOD OF SYNTHESIS OF POLY-α-OLEFIN (VARIANTS) Russian patent published in 2001 - IPC

Abstract RU 2167879 C2

FIELD: organic chemistry, chemical technology, polymers. SUBSTANCE: invention describes the novel catalyst of olefin polymerization as azaborolinyl metal complexes of the general formula (I) where L means ligand of the formula (II) where L′ means cyclopentadienyl, pentamethylcyclopentadienyl; X means halogen atom; M means titanium, zirconium or hafnium; n = 0-3 and Lв - means Lewis base optionally. Invention describes also method of synthesis of poly-α-olefin (variants). EFFECT: increased activity of catalyst, use of very small amounts of catalyst. 15 cl, 4 tbl
