| titleOfInvention | Catalyst and method of producing polyethylene and copolymers of ethylene with alpha-olefins with narrow molecular weight distribution |
| abstract | FIELD: chemistry. n SUBSTANCE: invention relates to a method of producing polyethylene and copolymers of ethylene with alpha-olefins using a supported titanium-magnesium catalyst. A method is described for producing polyethylene and copolymers of ethylene with alpha-olefins with a narrow molecular weight distribution in suspension mode in a medium of a hydrocarbon solvent using a supported catalyst containing a titanium compound on a magnesium-containing support, where the method is distinguished by that, the catalyst used is made by reacting a solution of a magnesium-containing compound with a compound which triggers conversion of the magnesium-containing compound to a solid magnesium-containing support. The magnesium-containing compound used is butylmagnesium chloride in a solution of R 2 O ether, where R=butyl or i-amyl, and the compound used for triggering conversion of the magnesium containing compound to a solid magnesium-containing support is a composition which contains a product of reacting alkylchloro silane with formula: R' k SiCI 4-k where: R' is alkyl or phenyl, k=1, 2, with silicon tetraalkoxide Si(OEt) 4 in molar ratio Si(OEt)/SiCl=0 - 025 and dialkylaromatic ether. The catalyst is used together with a co-catalyst - aluminium trialkyl. The molecular weight regulator of the polymer of copolymer used is hydrogen in amount of 10-50 vol. %. n EFFECT: high output of polyethylene with high melt flow index (MFI(5)=8-100) and narrow molecular weight distribution (Mw/Mn=3,8-5,4) at low hydrogen concentration in the reaction medium. n 3 cl, 1 tbl, 8 ex |
