TITANIUM-CONTAINING COMPONENT OF CATALYST FOR ETHYLENE POLYMERIZATION, A CATALYST FOR ETHYLENE POLYMERIZATION AND A METHOD OF ETHYLENE POLYMERIZATION USING THIS CATALYST Russian patent published in 1997 - IPC

FIELD: chemical technology, catalysts. SUBSTANCE: titanium-containing component of catalyst for ethylene polymerization is obtained by interaction (A) of solid magnesium-aluminium complex that contains magnesium, halogen, aluminium and alkoxy-group and/or alcohol having at least 6 carbon atoms, and (B) titanium tetravalent compound. The solid magnesium-aluminium complex (A) is obtained by interaction of (a-1) magnesium solution formed from halogen-derivative of magnesium, alcohol and having at least 6 carbon atoms, and hydrocarbon solvent, and (a-2) organoaluminium compound. Invention proposes also a method of ethylene polymerization that involves ethylene polymerization or copolymerization of ethylene and alpha-olefin with 3-20 carbon atoms in the presence of ethylene polymerization catalyst that consists of (1) the above indicated titanium-containing catalyst component of ethylene polymerization and (2) component based on organoaluminium compound. EFFECT: improved method of polymerization, enhanced effectiveness of catalyst. 7 cl, 6 tbl, 1 dwg
