Abstract

Procedeu pentru obtinerea unui catalizator utiluzat la polimerizarea olefinelor, caracterizat prin aceea ca se supune tratarii termice un suport de oxid de magneziu activat în pat fluidizat cu azot uscat la temperatura de 100...600 degree C, de preferinta 150...400 degree C, timp de 1...12h, de preferinta 3...6h, impregnat cu un compus de titan cu formula generala Ti(OR)n Cl4-n, unde n este 0...4, iar R este un radical alchil C2...C6, dupa care se reduce cu o halogenura de alchilaluminiu, de preferinta sesviclorura de etil-aluminiu.A process for the preparation of a catalyst used in the polymerization of olefins, characterized in that a dry oxide-supported magnesium oxide support is thermally treated at a temperature of 100 ... 600 ° C, preferably 150 ... 400 ° C C for 1 ... 12 hours, preferably 3 to 6 hours, impregnated with a titanium compound of the general formula Ti (OR) n Cl4-n where n is 0-4 and R is a radical C2 -C6 alkyl, then reduced with an alkylaluminium halide, preferably ethyl-aluminum sesquichloride.
