The present invention relates to a process for homopolymerization of ethylene or copolymerization of ethylene with alpha-olefins by contacting ethylene or ethylene and alpha-olefin with a catalyst composition comprising: (a) a solid catalyst precursor comprising at least one vanadium compound, at least one magnesium compound and a polymeric material or a solid catalyst precursor comprising at least one vanadium compound, at least one further transition metal compound and/or at least one alcohol, at least one magnesium compound and a polymeric material; and (b) a cocatalyst comprising an aluminum compound.

Process for the polymerization of olefins

The present invention relates to a catalyst composition for polymerization of olefins comprising: (a) a solid catalyst pre cursor comprising at least one vanadium compound, at least one magnesium compound and a polymeric material or a solid catalyst precursor comprising at least one vanadium compound, at least one further transition metal compound and/or at least one alcohol, at least one magnesium compound and a polymeric material; and (b) a cocatalyst comprising at least one aluminum compound; and to a method for preparing a catalyst composition according to the present invention, comprising the steps of: (a) combining the components of the solid catalyst precursor; and (b) activating the catalyst precursor with aluminum compound.

Catalyst composition for polymerization of olefins and method for preparing the same

The present invention relates to a catalyst composition for homopolymerization or copolymerization of olefins comprising: (a) a solid catalyst precursor comprising a transition metal compound of group IVB, VB, or VIB of the periodic table, a magnesium compound and aliphatic polyketone particles; and (b) a cocatalyst comprising an aluminum alkyl, an aluminoxane or mixtures thereof; and a process for homopolymerisation or copolymerisation of olefins.
