Abstract
Catalytic composition which may be used for the polymerization of alpha-olefins, comprising: PA1 (a) a solid catalyst comprising on titanium trichloride (TiCl.sub.3), PA1 (b) a non-halogen-containing cocatalyst comprising at least one non-halogen-containing organoaluminium compound, characterized in that the non-halogen-containing cocatalyst additionally contains at least one aminoalane containing no active hydrogen. Such a catalytic system may additionally contain a tertiary constituent chosen from oxygenated organosilicon compounds.
