Abstract
The present invention relates to a supported catalyst composition and a method for making the supported catalyst composition and its use in a process for polymerizing olefin(s). In particular, the invention is directed to a method for making a supported catalyst composition by combining a heated bulky ligand metallocene-type catalyst system with a carrier or an optionally heated carrier.
