A process for the polymerisation of olefins in the gas phase is carried out in the presence of a supported transition metal catalyst. The process involves a prepolymerisation step which may be performed in-situ and in particular the prepolymer may be prepared in the dry phase. The catalyst may for example comprise a constrained geometry transition metal complex supported on silica and used in the presence of an activator. The prepolymerisation step unables the activity of the catalyst to be improved.

L'invention concerne un procédé de polymérisation d'oléfines en phase gazeuse, effectué en présence d'un catalyseur de métal de transition sur un support. Ce procédé comprend notamment une étape de prépolymérisation, pouvant être effectuée in situ et destinée en particulier à préparer le prépolymère en phase sèche. Le catalyseur peut par exemple renfermer un complexe à métaux de transition à géométrie contrainte sur un support de silice, ce complexe étant utilisé en présence d'un activateur. Cette étape de prépolymérisation favorise l'activité dudit catalyseur.
