Abstract

L’invention concerne un procédé de préparation d’un polyéthylène qui comprend la polymérisation de l’éthylène en phase gazeuse en présence d’un système catalytique supporté sur un support inorganique poreux, le système catalytique étant à base au moins d’un métallocène de terre rare de formule (Ia) ou (Ib) et d’un organomagnésien. Il permet la synthèse de polyéthylènes semi-cristallins de très hautes masses molaires tels que le UHMWPE.
