METHOD OF PREPARING CATALYST FOR POLYMERIZATION OF ETHYLENE AND COPOLYMERIZATION THEREOF WITH ALPHA-OLEFINS Russian patent published in 1997 - IPC

Abstract SU 1190579 A1

FIELD: catalysts for olefin polymerization processes. SUBSTANCE: method including reducing titanium tetrachloride by magnesium halide compound is distinguished by using, as magnesium halide compound, a solid non-solvated alkyl or hydride magnesium derivative with general formula RaMgX2-a wherein R is H, butyl, or heptyl; a = 0.5-2.0; and x is Cl, Br or I, reduction being carried out at magnesium compound to titanium tetrachloride molar ratio from 30 to 600. EFFECT: improved procedure.
