Patent

CA 2213751

A method for controlling fouling in a prepolymerization reactor is disclosed and comprises combining a supported metallocene catalyst system, an alpha olefin monomer feed, and added hydrogen under suitable prepolymerization reaction conditions. This method is also useful for the control of agglomeration during a prepolymerization reaction.

Méthode pour éliminer l'encrassement dans un réacteur de prépolymérisation, consistant à combiner un système catalytique de métallocène sur support avec une alimentation de monomère alpha-oléfinique, et à ajouter de l'hydrogène dans des conditions de réaction de prépolymérisation appropriées. La méthode est utile aussi pour empêcher l'agglomération durant une réaction de prépolymérisation.
