<p>Disclosed are catalyst systems and methods of making the catalyst systems/supports for the polymerization of an olefin containing a solid titanium catalyst component and an antistatic agent, Also disclosed are methods of making a polyolefin involving contacting an olefin with a catalyst system containing an antistatic agent. The use of the antistatic agent added to the catalyst system can improve flowability and/or dispersibility of the catalyst system.</p>
