Abstract

Ce procédé de polymérisation de monomères oléfiniques consiste à former un courant de fluide contenant un catalyseur, à introduire de manière continue ledit courant de fluide dans un réacteur de polymérisation allongé (1) comprenant au moins deux chambres successives (12a) séparées par des plaques séparatrices (12b) dont le diamètre est légèrement inférieur à celui du réacteur de polymérisation (1), à introduire dans ledit réacteur (1) un monomère, et, éventuellement, un co-catalyseur et un donneur dans des conditions de température susceptibles de polymériser ladite oléfine, tandis qu'un écoulement mixte est maintenu dans lesdites chambres (12a) pour polymériser le monomère et, éventuellement, le comonomère dans le fluide, et à enlever la suspension de polymère ainsi produite du réacteur de polymérisation.
