The object is to provide a catalyst component for polymerization of ethylene which can produce an ethylene polymer of high molecular weight which has substantially only an ethyl branch. The catalyst component for polymerization of ethylene is obtained by contacting the following components (A), (B) and (C): component (A): a meso-metallocene compound, component (B): a solid co-catalyst component comprising a particulate carrier and a compound which ionizes a metallocene compound to form an ionic complex and which is supported on the particulate carrier, and component (C): an organoaluminum compound.

Catalyst systems and methods for making and using the same are described herein. A catalyst system can include at least three catalysts. The three catalysts include a metallocene catalyst, a first non-metallocene including a ligand complexed to a metal through two or more nitrogen atoms, and a second non-metallocene including a ligand complexed to a metal through one or more nitrogen atoms and an oxygen atom.
