Abstract
1. Катализатор для полимеризации этилена и сополимаризации его с α-олефинами, содержащий хлорид титана и магнийсодержащий носитель, отличающийся тем, что, с целью повышения активности и способности катализатора к регулированию индекса расплава полимера в присутствии водорода, катализатор содержит в качестве хлорида титана тетрахлорид титана, в качестве носителя - носитель состава MgCl• P, где Р - полимерное углеводородное соединение с мольным отношением С/Н, равным 2,2 - 2,3, входящее в структуру MgClв количестве 8,2 - 16,6% от массы носителя, и дополнительно - триэтилалюминий при следующем соотношении компонентов, мас.%:Тетрахлорид титана - 0,8 - 8,4Триэтилалюминий - 1,9 - 9,2Магнийсодержащий носитель - Остальное2. Способ приготовления катализатора для полимеризации этилена и сополимеризации его с α-олефинами путем смешения тетрахлорида титана с магнийсодержащим носителем состава MgCl• P, где Р - полимерное углеводородное соединение с мольным отношением С/Н, равным 2,2 - 2,3, входящее в структуру MgCl в количестве 8,2 - 16,6% от массы носителя, с последующей сушкой катализаторной массы, отличающийся тем, что, с целью получения катализатора с повышенными активностью и способностью к регулированию индекса расплава полимера в присутствии водорода, катализаторную массу перед сушкой дополнительно обрабатывают триэтилалюминием при мольном отношении Al/Ti, равном 1 - 10, и температуре 0 - 100C.1. Catalyst for the polymerization of ethylene and its copolymerization with α-olefins, containing titanium chloride and a magnesium-containing carrier, characterized in that, in order to increase the activity and ability of the catalyst to regulate the melt index of the polymer in the presence of hydrogen, the catalyst contains titanium tetrachloride as titanium chloride , as a carrier, a carrier of MgCl • P composition, where P is a polymeric hydrocarbon compound with a C / H molar ratio of 2.2 - 2.3, which is included in the MgCl structure in an amount of 8.2 - 16.6% by weight of the carrier, and add It is triethylaluminum in the following ratio of components, wt.%: Titanium tetrachloride - 0.8 - 8.4. Triethylaluminum - 1.9 - 9.2. Magnesium-containing carrier - Else2. The method of preparation of the catalyst for the polymerization of ethylene and its copolymerization with α-olefins by mixing titanium tetrachloride with a magnesium-containing carrier MgCl • P, where P is a polymeric hydrocarbon compound with a C / H molar ratio of 2.2 - 2.3, which is part of MgCl in the amount of 8.2 - 16.6% by weight of the carrier, followed by drying the catalyst mass, characterized in that, in order to obtain a catalyst with increased activity and ability to regulate the melt index of the polymer in the presence of hydrogen, the catalyst mass prior to drying further treated with triethylaluminum in a molar ratio Al / Ti, equal to 1 - 10 and a temperature of 0 - 100C.
