Zusammenfassung:Catalyst precursor for polyethylene production from ethylene comprises a chromium complex. Catalyst precursor for polyethylene production comprises a chromium complex with the following formula: Y, Z : C, N, S, P or O; R : aryl or alkyl; x : 1 or 2, depending on the valence of Y and Z; n : 2 or 3. An independent claim is also included for producing polyethylene by polymerizing ethylene in the presence of a catalyst precursor as above and a methyl aluminoxane cocatalyst. [Image].
