Two zirconium complexes,Bis[N-(3-tert-butylsalicylidene)allylaminato]zirconium dichloride(4)and Bis [N-(3-tert-butylsalicylidene)-iso-butylaminato]zirconium dichloride(5),were prepared and characterized.The molecular structure of complex 4 has been determined by X-ray crystallographic analysis.The corresponding polymer-incorporated zirconium catalyst 6 was obtained by the co-polymerization of the olefin group of catalyst 4 with styrene in the presence of a radical initiator.All catalysts (4,5 and 6)have been investigated for ethylene Polymerization.These catalysts exhibit high activity up to 3.7×106gPE·(mol Zr)-1·h-1 in the presence of modified methylaluminoxane(MMAO)as a co-catalyst.
