Abstract

Procédé pour la polymérisation de l'éthylène ou la copolymérisation de l'éthylène avec des alpha -oléfines en C3 -C 15 en solution, en suspension ou en phase gazeuse, à une température de 20 à 250 degrés C et une pression de 1 à 50 bars, en présence d'un catalyseur mélangé consistant en un composé chloré du titane-III et un composé organique de l'aluminium avec réglage du poids moléculaire par l'hydrogène. On utilise en tant que composé organique de l'aluminium un composé de trialkylaluminium en proportions de 0,1 à 20 moles par mole du composé de titane-III et on ajoute aux monomères de l'oxygène à une concentration de 0,001 à 0,1 % en volume par rapport à l'éthylène. Le procédé selon l'invention permet d'agir à la fois sur le niveau du poids moléculaire et sur la répartition des poids moléculaires.
