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 AS OF THE PROCATALYST IN SPECIFIED POLYMERIZATION CONDITIONS, IS AS > 3.2 WHEREIN AS = ((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 I MEANS LOW MELT FLOW RATE POLYMERIZATION AND THE PRESENCE OF THE UPPER INDEX I MEANS HIGH MELT FLOW POLYMERIZATION. THIS MEANS THAT THE CATALYST ACTIVITY IS RELATIVELY INDEPENDENT OF THE PRESENCE OF CHAIN TRANSFER AGENTS.
