Abstract

L'invention concerne un procédé de polymérisation multiphase pour la production d'oléfines, procédé consistant à mettre en contact des oléfines avec un catalyseur homogène, ou un système de catalyseur homogène, à une température comprise entre le point de fusion du polymère anhydre, et 80 °C en dessous du point de fusion du polymère anhydre en présence d'un hydrocarbure fluoré. L'invention concerne également un procédé de production de polyéthylène consistant à mettre en contact un catalyseur homogène ou un système de catalyseur homogène avec de l'éthylène et 0 à 40 % en poids d'un ou plusieurs comonomères oléfiniques en C3 à C40, en présence d'un hydrocarbure fluoré et, éventuellement, d'un solvant hydrocarburé, à une température inférieure au point de fusion du milieu réactionnel. L'invention concerne en outre un procédé de production de polypropylène consistant à mettre en contact un catalyseur homogène ou un système de catalyseur homogène avec du propylène et 0 à 50 % en poids d'un ou plusieurs comonomères d'éthylène et d'oléfines en C4 à C40, en présence d'un hydrocarbure fluoré et, éventuellement, d'un solvant hydrocarburé, à une température inférieure au point de fusion du milieu réactionnel.
