Abstract
It has been shown that 8-quinolinolate zirconium complexes ZrOx nCl 4-n can be synthesized by the mechanochemical method using zirconium tetrachloride and sodium quinolinolate as starting materials. The ZrOx nCl 4-n – Et 1.5AlCl 1.5 system exhibits a moderate catalytic activity and high selectivity in ethylene oligomerization. The system activity increases symbatically with the number of chelating ligands in the zirconium precursor. The ZrOx nCl 4-n - polymethylalumoxane system exhibits a negligible catalytic activity in ethylene polymerization. An explanation of the phenomena observed is proposed.
