Abstract
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.
