摘要（英）：

The present invention provides a supported antistatic polymerization catalyst and a method for preparing a olefin polymerization catalyst. The method comprises contacting a porous metal oxide, a transition metal catalyst system and an antistatic additive, wherein said antistatic additive comprises a polysulfone and a solvent for said polysulfone and wherein said catalyst is further characterized in that said antistatic additive is added to said porous metal oxide in an amount of from 5,000 to 50,000 parts per million by weight based on the weight of said porous metal oxide. The said catalyst is further characterized in that the porous metal is silicon dioxide having a pore volume of from 0.1 to 5 mL/g.
