Patent

CA 2223258

The invention relates to a supported, prepolymerized metallocene catalyst system as well as its production and use in olefin polymerization. The method for producing the prepolymerized catalyst system involves prepolymerizing a metallocene catalyst system containing a volume of solution that is the equivalent of or less than the total pore volume of the supported catalyst system.

L'invention concerne des systèmes catalyseurs comprenant un métallocène prépolymérisé, sur un support, ainsi que leur préparation et leur utilisation pour la polymérisation d'oléfines. Le procédé de préparation du système catalyseur prépolymérisé consiste à prépolymériser un système catalyseur comprenant un métallocène et contenant un volume d'une solution qui est égal ou inférieur au volume total des pores du système catalyseur sur support.
