Abstract
Methods for scale-up from a pilot plant to full production of a bimodal polymer product having a density, melt index, and a melt index ratio are provided herein. The methods provide for adjusting reactor conditions and catalyst ratio of a bimodal catalyst system to optimize the transition from single catalyst to bimodal polymer compositions on a full-scale process plant consistent with pilot plant development.
