Abstract

Abstract Translated from German Die Desaktivierung von Katalysatorsystemen aus einer Übergangsmetallverbindung und einer organischen Aluminiumverbindung, die zur Polymerisation von Ethylen oder zur Copolymerisation von Ethylen mit einem α-Olefin bei Drücken von 300 bis 3.500 bar und Temperaturen zwischen 150 und 350 °C eingesetzt werden, erfolgt mit Polyglykolen. The deactivation of catalyst systems from a transition metal compound and an organic aluminum compound, which are used for the polymerization of ethylene or for the copolymerization of ethylene with an α-olefin at pressures of 300 to 3,500 bar and temperatures between 150 and 350 ° C, is carried out with polyglycols.
