was prepared and the effect of the content of this supported catalyst on catalytic activity was investigated The activity is greatly influenced by the content of Ti
Mg and SiO2 The activity of the catalyst cab be improved by adding SiO2 with good flowability and treating MgCl2-SiO2 with MAO
and the influence of Mg on the activity of Ti is also important for improving the catalytic activity.Another supported catalyst.CpTi-(dbm)Cl2/MgCl2-ZnCl2-SiO2/MAO
whereas SiO2 was treated by MAO and ZnCl2 previously
was prepared and its catalysis for ethylene polymerization was investigated The activity increases with increasing the ZnCl2 in feed
while the molecular weight of polymers decreases and the molecular weight distribution broadens.
