摘要
Catalyst system usable for the polymerisation of alpha-olefins, including (a) a catalytic solid based on titanium trichloride (TiCl3), (b) a nonhalogenated cocatalyst including at least one nonhalogenated organoaluminium compound, characterised in that the nonhalogenated cocatalyst additionally contains at least one aminoalane containing no active hydrogen. Such a catalyst system may additionally contain a third constituent chosen from the organic oxygen compounds of silicon.
