Abstract

L'invention est relative à un procédé de polymérisation de l'éthène en plusieurs étapes. Selon l'invention, on polymérise à la première étape en phase liquide dans des hydrocarbures en C3 à C6 et on polymérise en phase gazeuse à la dernière étape, tout en effectuant éventuellement une ou plusieurs étapes de polymérisation entre la première et la dernière. Le procédé permet d'obtenir un polyéthène en poudre bien roulante à grande masse volumique.
