Method for the preparation of ethylene polymer compositions

Abstract

The present invention provides a method for the preparation of an ethylene polymer composition having a density of 0.86-0.94 g/cm³ and an intrinsic viscosity [η] of 1-6 dl/g using an olefin polymerization catalyst comprising a transition metal compound containing a ligand having a cycloalkadienyl skeleton and an organoaluminium oxy-compound. A method for the preparation of an ethylene polymer composition having density of 0.87-0.93 g/cm³ and an intrinsic viscosity [η] of 0.5-6 dl/g is also provided.
