| titleOfInvention | CATALYSOP FOR PREPARATION OF POLYETHYLA AND POLYMEPOB ETIHEHA C-OLEFHAMI AND METHOD OF ITS PREPARATION |
| abstract | 1. Catalyst for producing polyethylene and copolymers of ethylene with α-olefins with a wide molecular weight distribution, containing a transition metal compound with a magnesium-containing carrier, characterized in that, in order to increase the activity of the catalyst and increase its ability to regulate the polymer melt index in the presence of hydrogen , the catalyst contains as a transition metal compound vanadium tetrachloride VCl or vanadium oxitrochloride VOCl, and as a carrier - a solid product of the composition: Mg • Al • Si • Cl • R, where x = 8.1 - 9.6; y = 0.074 - 0.56; m = 0.11 - 0.79; n = 16 - 20; p = 2.9 - 13.0, containing, wt.%: Mg - 19 - 23Al - 0.2 - 1.5Si - 0.3 - 2.2Cl - 60 - 72The hydrocarbon part of R - 4.2 - 19 with the following ratio of components, wt.%: VCl or VOCl- 3.0 - 13.2 Carrier - The rest2. A method of producing a catalyst for producing polyethylene and copolymers of ethylene with α-olefins, including the interaction of a transition metal compound with a magnesium-containing carrier, characterized in that, in order to produce a catalyst with increased activity and ability to regulate the polymer melt index in the presence of hydrogen, as a transition compound metal used tetrachloride, vanadium VCl or vanadium oxytrichloride VOCl, and as a carrier - a solid product of the composition: Mg • Al • Si • Cl • R, where x = 8.1 - 9.6; y = 0.074 - 0.56; m = 0.11 - 0.79; n = 16 - 20; p = 2.9 - 13.0, containing, in wt.%: Mg - 19 - 23Al - 0.2 - 1.5Si - 0.3 - 2.2Cl - 60 - 72H-hydrocarbon part R - 4 , 2 - 19.0 and the interaction is carried out in the presence of carbon tetrachloride at 20 - 100С. |
