Abstract

A process for the polymerization of two or more ethylene units, using a complex of pialilcromo as catalyst, comprising the improvement of using as a catalyst a complex of pi-alil-chromium in which at least a portion of complex is at least in the valence state [II] of chromium and the complex is deposited on a support with a large specific surface.
