| titleOfInvention | Method of producing catalyst for polymerisation of ethylene and copolymerisation of ethylene with alpha-olefins |
| abstract | FIELD: chemistry. n SUBSTANCE: described is a method for gas-phase polymerisation of ethylene and copolymerisation of ethylene with alpha-olefins in the presence of a supported catalyst with particle size ≥20 mcm, obtained by reacting a solution of an organomagnesium compound with a compound which enables to convert the organomagnesium compound into a solid magnesium-containing support, followed by treating the solid product with a titanium compound, where as the organomagnesium compound butylmagnesium chloride in an ether solution R 2 O is used, where R is butyl or i-amyl, and the compound required to convert the organomagnesium compound into a solid magnesium-containing support is a composition which includes a reaction product of an alkylchlorosilane composition R' k SiCl 4-k , where R' is an alkyl or phenyl, k=1, 2, and silicon tetraalkoxide Si(OEt) 4 in molar ratio SiCl/Si(OEt)=0.4-14, molar ratio Si/Mg=1-2 and temperature 10-40°C. n EFFECT: obtaining polyethylene with high output and the required particle size of 450-800 mcm, with a narrow particle size distribution. n 2 cl, 1 tbl, 11 ex |
