Notes:
The chemistry of three-component coordination catalysts for the polymerization of α-olefins is very complex. The present investigation was initiated to elucidate the chemistry involved in the interaction of third-component compounds such as hexamethylphosphoric triamide, tributylamine, triphenylphosphine, or dimethylformamide with ethylaluminum dichloride. The present chemical and spectral data demonstrate that ethylaluminum dichloride and third-component compounds form stable complexes even at temperatures up to 100°C. in the absence of solvents or in homogeneous solutions. These data are in agreement with the fact that organoaluminum compounds form stable complexes with a variety of electron-donor compounds. The ethylaluminum dichloride third-component complexes in combination with titanium(III) chloride produce highly stereospecific catalysts for the polymerization of α-olefins.
