SOLID COMPONENT OF CATALYST FOR POLYMERIZATION OF ETHYLENE, METHOD OF ITS PRODUCTION, CATALYST FOR POLYMERIZATION OF ETHYLENE AND METHOD FOR PRODUCTION OF POLYETHYLENE BY POLYMERIZATION OF ETHYLENE IN THE PRESENCE OF CATALYST Russian patent published in 1997 - IPC

FIELD: polymerization of ethylene and copolymerization of ethylene with α-olefins. SUBSTANCE: desired solid component contains product of consequent dissolution of tetra-C₂-C₄-alkoxy titanium and magnesium chloride in ethyl acetate, molar ratio of tetra-C₂-C₄-alkoxy titanium and magnesium chloride is 0.99: 1.00 respectively. Then activated silica gel is impregnated with thus prepared solution, ethyl acetate is evaporated at temperatures up to 60 C. Solid residue is treated by solution of aluminium ethyl sesquichloride in inert hydrocarbon to isolate solid product which comprises 1.4-2.2 gram-atom of magnesium, 5.3-7.5 gram-atom of chlorine and 0.4-0.7 butoxy groups per 1 gram-atom of titanium. Said treatment is carried out within 15 min at 25 C, it is followed by isolation and washing of desired product. EFFECT: improves quality of desired product, improves efficiency of the method. 9 cl
