Beschreibung
Zusammenfassung:	Prodn. of supported catalysts for ethylene polymerisation or copolymerisation of ethylene with other alpha -olefins comprises (a) reacting a soln. of an organomagnesium cpd. (I) with an organic halide (II) at -20 to +60 degrees C in a halide/Mg molar ratio of at least 0.5 and (b) impregnating the resulting support with Ti or V cpds.. (I) is of formula MgPh2.nMgCl2.mR2O (1), where n = 0.37-0.7; m = more than 2; and R2O is an ether.
