摘要：

The activity of various vanadium-based supported catalysts for the polymerization of ethene at high temperature (160-degrees) was studied. The catalytic systems were prepared by co-milling of vanadium trichloride with different metal chlorides used as supports. Their characterization was made by X-ray diffraction and B.E.T. methods. The oxidation state of vanadium in the supported catalyst after reaction with the aluminium alkyl, was determined by a potentiometric method. The effect of several parameters of catalytic systems on activity is discussed.
