METHOD OF PREPARING APPLIED CATALYST FOR ETHYLENE POLYMERIZATION AND COPOLYMERIZATION OF ETHYLENE WITH α-OLEFINS Russian patent published in 1995 - IPC

Abstract RU 2047355 C1

FIELD: organic chemistry. SUBSTANCE: method of preparing applied catalyst for ethylene polymerization and copolimerization of ethylene with a-olefins by treatment of magnesium chloride with alcohol at molar ratio ROH/Mg 0.5-2 where R C₂H₅-C₈H₁₇ followed by applying vanadium compound on the prepared magnesium-containing carrier in the presence of haloidorganic compound of the formula CH_nCl_4-n where n 0-2 at the ratio CH_nCl_4-n/V 10-60 mole/mole. Prepared product is treated with aluminiumorganic compound of composition AlR*x

Cl_3-x at molar ratio to ROH 0.2-1.0 where R₁-C₂H₅, i-C₄H₉; X 1-3. EFFECT: improved method of catalyst preparing. 2 tbl
