ABSTRACT:
Cocatalytic composition resulting from bringing an organoaluminium halide (A) into contact with an electron-donating organic compound (ED) selected from esters, amides and ketones, the organoaluminium halide (A) possessing an atomic ratio halogen (X)/aluminium (Al) of greater than 1 and less than 1.3, the halide (A) and the compound (ED) being employed in a mole ratio halide (A)/compound (ED) of greater than 20. Catalytic systems which are usable for the polymerization of alpha-olefins, comprising such a cocatalytic composition and a solid based on titanium trichloride complexed with an electron-donating compound.
