Abstract
The present invention provides a supported catalyst system comprising: a bridged group 4 metallocene compound, an iron compound, specifically a 2,6-bis(imino)pyridyl iron complex, a support material and an activator. The present invention further provides a process for polymerization of monomers (such as olefin monomers) comprising contacting one or more monomers with the above supported catalyst systems.
