A method for producing a multimodal ethylene-based polymer comprising: passing ethylene monomer, at least one C 3 -C 12 comonomer, solvent, and optionally hydrogen in both a first solution polymerization reactor, and a second solution polymerization reactor, wherein the first solution polymerization reactor or the second solution polymerization reactor receives both a first catalyst and a second catalyst, and wherein a third catalyst is passed to the other of the first or second solution polymerization reactors in which the first and second catalysts are not present; producing the multimodal ethylene-based polymer having a first ethylene-based component, a second ethylene-based component, and a third ethylene-based component, wherein the first ethylene-based component is a polymerized reaction product of ethylene monomer and C 3 -C 12 comonomer catalyzed by the first catalyst, the first ethylene-based component having a first density (ρ 1 ); the second ethylene-based component is a polymerized reaction product of ethylene monomer and C 3 -C 12 comonomer catalyzed by the second catalyst, the second ethylene-based component having a second density (ρ 2 ); and the third ethylene-based component is a polymerized reaction product of ethylene monomer and C 3 -C 12 comonomer catalyzed by the third catalyst, the third ethylene-based component having a third density (ρ 3 ); wherein ρ 2 and ρ 1 have different values. passing ethylene monomer, at least one C 3 -C 12 comonomer, solvent, and optionally hydrogen in both a first solution polymerization reactor, and a second solution polymerization reactor, wherein the first solution polymerization reactor or the second solution polymerization reactor receives both a first catalyst and a second catalyst, and wherein a third catalyst is passed to the other of the first or second solution polymerization reactors in which the first and second catalysts are not present; producing the multimodal ethylene-based polymer having a first ethylene-based component, a second ethylene-based component, and a third ethylene-based component, wherein the first ethylene-based component is a polymerized reaction product of ethylene monomer and C 3 -C 12 comonomer catalyzed by the first catalyst, the first ethylene-based component having a first density (ρ 1 ); the second ethylene-based component is a polymerized reaction product of ethylene monomer and C 3 -C 12 comonomer catalyzed by the second catalyst, the second ethylene-based component having a second density (ρ 2 ); and the third ethylene-based component is a polymerized reaction product of ethylene monomer and C 3 -C 12 comonomer catalyzed by the third catalyst, the third ethylene-based component having a third density (ρ 3 ); the first ethylene-based component is a polymerized reaction product of ethylene monomer and C 3 -C 12 comonomer catalyzed by the first catalyst, the first ethylene-based component having a first density (ρ 1 ); the second ethylene-based component is a polymerized reaction product of ethylene monomer and C 3 -C 12 comonomer catalyzed by the second catalyst, the second ethylene-based component having a second density (ρ 2 ); and the third ethylene-based component is a polymerized reaction product of ethylene monomer and C 3 -C 12 comonomer catalyzed by the third catalyst, the third ethylene-based component having a third density (ρ 3 ); wherein ρ 2 and ρ 1 have different values. <EOS>
