## Abstract The ethylene polymerization by Cp~2~ZrCl~2~/MAO (Cp = η^5^: cyclopentadienyl; MAO = methyl aluminoxane) and CpZrCl~3~/MAO have been studied. The MW and PD (= __M__~__w__~/__M__~__w__~) of polymers obtained after 2.5‐60 min are the same, which indicate short chain lifetime. The values of
