ABSTRACT:
A two-stage polymerization process using a modified supported catalyst gives ethylene polymers with very good processability and excellent finished component properties. The supported catalyst used is formed by reaction of a magnesium alcoholate with a titanium-IV compound in suspension and subsequent reaction with a halogen-containing organoaluminum compound and activation of the solid thus obtained by an aluminum trialkyl or aluminum isoprenyl.
