摘要：A method for production of catalytic systems of the Ziegler-Natta type ischaracterised in comprising the following steps: A) bringing an inorganic metal oxide anda magnesium compound of formula MgRnX2-n into contact, where X = independently,fluorine, chlorine, bromine, iodine, hydrogen, NR2, OR, SR, SO3R or OC(O)R and R =independently, C1-C20 linear, branched, or cyclic alkyl, a C2-C10 alkenyl, an alkylaryl with1-10 C atoms in the alkyl group and 6-20 C atoms in the aryl group, or a C6-C18 aryl andn =1 or 2, then, B) bringing the intermediate product obtained in step A) into contact witha halogenating reagent, C) bringing the intermediate product obtained in step B) intocontact with a) a tetravalent titanium compound, b) a metallo-organic compound ofgroup 3 of the periodic system and c) optionally, an electron-donor compound and D)washing the product obtained in step C) with an aprotic solvent. The invention furtherrelates to a catalytic system obtained as above and a method for the polymerisation ofolefins.
