A process to form an ethylene-based polymer including polymerizing ethylene and at least one asymmetrical polyene comprising an “alpha, beta unsaturated-carbonyl end” (“α,β unsaturated-carbonyl end”) and a “C—C double bond end,” wherein the polymerization takes place in the presence of at least one free-radical initiator; and wherein the polymerization takes place in a reactor configuration comprising at least two reaction zones, reaction zone 1 and reaction zone i (i≧2), wherein reaction zone i is downstream from reaction zone 1.
