Abstract

Dichlorobis(3‐hydroxy‐2‐methyl‐4‐pyrone)Zr(IV) was grafted onto different inorganic supports, namely SiO~2~, MAO‐modified SiO~2~, MCM‐41, Al~2~O~3~, and MgO. The resulting supported catalysts were shown to be active in ethylene polymerization using methylaluminoxane (MAO) as the catalyst. Catalysts were characterized by Rutherford Backscattering Spectrometry (RBS) and nitrogen adsorption method. The highest catalyst activities were observed for the zirconium complex supported on MCM‐41. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010

This paper describes the preparation of some active organometallic species derived from nickel, titanium and zirconium fixed on the surface of different supports and their behaviour for the catalytic polymerization of ethylene. In the case of nickel, the transition metal species were attached to cro
