## Abstract The ethylene polymerization by Cp~2~ZrCl~2~/MAO (Cp = Ξ·^5^: cyclopentadienyl; MAO = methyl aluminoxane) and CpZrCl~3~/MAO have been studied. The MW and PD (= __M__~__w__~/__M__~__w__~) of polymers obtained after 2.5β60 min are the same, which indicate short chain lifetime. The values of
## Abstract In this work, ethylene was polymerized by using Cp~2~ZrCl~2~ supported on silica pretreated with methylaluminoxane (MAO) as the catalyst system. The influence of the conditions for the preparation of the heterogeneous catalyst, such as temperature, washing method of the catalytic solid,
