혼합촉매 조성물은 유기알루미늄 할로겐화물(A)을 에스테르, 아미드와 케톤에서 선택한 전자-공여 유기 화합물(ED)와 접촉하여 생성되고, 유기알루미늄 할로겐화물(A)은 1 이상과 1.3 이하의 할로겐 (X)/알루미늄(AL)의 원자비를 갖고 화합물(ED)은 20 이상의 할로겐화물(A)/화합물(ED)의 몰비로 사용된다. 알파-올레핀의 중합에 이용할 수 있는 촉매계는 이와같은 혼합촉매 조성물과, 전자-공여 화합물과 착화된 삼염화 티타늄을 주재로 한 고체로 이루어진다. 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.
