A series of novel non-metallocene catalysts with silicon bridge salicylaldehyde ligands were prepared by salicylaldehyde or its derivatives reacted with dichlorodimethylsilane and sodium borohydride as reductant.Then treated with transition metal halides of TiC14, ZrCl4 and HfCl4.The structures and properties of the catalysts were characterized by 1H NMR and Elemental Analysis.
