METHOD OF OBTAINING VANADIUM-MAGNESIUM CATALYST OF ETHYLENE POLYMERISATION AND COPOLYMERISATION OF ETHYLENE WITH ALPHA-OLEFINS Russian patent published in 2013 - IPC B01J37/00 C08F4/654 B01J31/36 C08F10/02

Abstract RU 2502560 C1

FIELD: chemistry.

SUBSTANCE: invention relates to field of catalyst. Described is method of obtaining catalyst for ethylene polymerization and copolimerisation of ethylene with alpha-olefins, containing vanadium compound on magnesium-containing carrier, which is obtained by interaction of solution of magnesium-organic compound with composition Mg(C₆H₅)₂nMgCl₂mR₂O, where; n=0.37-0.7, m=2, R₂O is ether with R=i-Am, n-Bu with chlorinating agent phenyltrichloromethane PhCCl₃with mole ratio PhCCl₃/MgR₂≥1.0, with further processing of carrier with alkylaluminium chloride and application of vanadium compound, with alkylaromatic ether being preliminarily introduced into magnesium organic compound at temperature 20-40°C with molar ratio alkylaromatic ether/Mg=0.05-0.2.

EFFECT: obtained catalyst makes it possible to obtain polymers with wide molecular-weight distribution, increased bulk density and high output.
