Zusammenfassung:	Embodiments of this disclosure includes processes of polymerizing a multi-modal polyethylene polymer. The process includes contacting ethylene and optionally one or more α-olefin monomers with at least two catalyst systems in a solution reactor at a reactor temperature of greater than 150°C. The at least two catalyst systems produce a vinyl end group count per 1000 carbon atoms is greater than 0.3. A first catalyst system of the at least two catalyst systems includes a first procatalyst; and a second catalyst system of the at least two catalyst systems comprises a second procatalyst having a reactivity ratio of less than 20, wherein the reactivity ratio of the first procatalyst is measured in a single reactor with only the first catalyst system in the presence of 1250 grams of ISOPAR-E, with a mol fraction of ethylene in solution of 0.709, and at a reactor temperature of at least 150°C.
