Beschreibung
Zusammenfassung:	A polymer comprising:polyethylene formed:in a polymerization reactor via a polymerization catalyst system comprising a first catalyst and a second catalyst; andby adjusting operating conditions of the polymerization reactor and an amount of the second catalyst fed to the polymerization reactor to control melt index (MI) and density of the polyethylene based on a target melt flow ratio (MFR) and a desired MWD and CD combination.
