摘要： Embodiments of a method for producing a multimodal ethylene-based polymer having a first, second, and third ethylene-based component, wherein the multimodal ethylene based polymer results when ethylene monomer, at least one C 3 -C 12 comonomer, solvent, and optionally hydrogen pass through a first solution, and subsequently, a second solution polymerization reactor. The first solution polymerization reactor or the second solution polymerization reactor receives both a first catalyst and a second catalyst, and a third catalyst passes through either the first or second solution polymerization reactors where the first and second catalysts are not already present. Each ethylene-based component is a polymerized reaction product of ethylene monomer and C 3 -C 12 comonomer catalyzed by one of the three catalysts.
