Methods for producing catalyst systems with increased productivity are disclosed. The methods may comprise providing a catalyst composition comprising a solvent and a single-site catalyst component, heating an inert gas to a temperature in a range of from about 100° C. to about 150° C., and spray drying the catalyst composition in the presence of the inert gas to form a spray-dried catalyst system. Additionally, the methods may comprise providing a catalyst composition comprising a solvent, an activator, a filler material, a metallocene catalyst, and a Group 15-containing catalyst; heating an inert gas to a temperature in a range of from about 100° C. to about 150° C.; and spray drying the catalyst composition in the presence of the inert gas to form a spray-dried catalyst system. |
