Abstract

The invention relates to a procatalyst for the production of ethylene polymers, which procatalyst comprises an inorganic support, a chlorine compound carried on said support a magnesium compound carried on said support, a titanium compound carried on said support, whereby the chlorine compound can be different from or the same as the magnesium compound and/or the titanium compound. The activity balance AB of the procatalyst in specified polymerization conditions, is AB >
3.2, wherein AB ~ [(A + A'):2] . [log (MFR2' : MFR2):
(A - A')] A means polymerization activity expressed as kg PE / g cat . h, MFR2 means the melt flow rate in g/min units at a load of 2,16 kg, according to the standard ISO 1133 the absence of the upper index ' means low melt flow rate polymerization and the presence of the upper index ' means high melt flow polymerization. This means that the catalyst activity is relatively independent of the presence of chain transfer agents.
