A high pressure polymerization process to form an ethylene-based polymer, the process comprising at least the following steps: polymerizing a reaction mixture comprising ethylene, using a reactor system comprising at least three ethylene-based feed streams and a reactor configuration that comprises at least four reaction zones, and wherein at least one of the following distributions a) through b), is met: (a) up to 100 wt% of the ethylene-based feed stream to the first reaction zone comes from a high pressure recycle, and/or up to 100 wt% of the last ethylene-based feed stream to a reaction zone comes from the output from a Primary compressor system; and/or (b) up to 100 wt% of the ethylene-based feed stream to first reaction zone comes from the output from a Primary compressor system, and/or up to 100 wt% of the last ethylene-based feed stream to a reaction zone comes from a high pressure recycle; and wherein each ethylene based feed stream to a reaction zone, independently, receives an output from two or more cylinders of the last compressor stage of a Hyper compressor system; and wherein the ethylene based feed stream to the first reaction zone is from 20 wt% to 60 wt% of the total ethylene based feed stream to the reactor configuration; and wherein the sum of the last two ethylene based feed streams to the reactor configuration is from 20 wt% to 80 wt% of the total ethylene based feed streams to the reactor configuration. polymerizing a reaction mixture comprising ethylene, using a reactor system comprising at least three ethylene-based feed streams and a reactor configuration that comprises at least four reaction zones, and wherein at least one of the following distributions a) through b), is met: (a) up to 100 wt% of the ethylene-based feed stream to the first reaction zone comes from a high pressure recycle, and/or up to 100 wt% of the last ethylene-based feed stream to a reaction zone comes from the output from a Primary compressor system; and/or (b) up to 100 wt% of the ethylene-based feed stream to first reaction zone comes from the output from a Primary compressor system, and/or up to 100 wt% of the last ethylene-based feed stream to a reaction zone comes from a high pressure recycle; (a) up to 100 wt% of the ethylene-based feed stream to the first reaction zone comes from a high pressure recycle, and/or up to 100 wt% of the last ethylene-based feed stream to a reaction zone comes from the output from a Primary compressor system; and/or (b) up to 100 wt% of the ethylene-based feed stream to first reaction zone comes from the output from a Primary compressor system, and/or up to 100 wt% of the last ethylene-based feed stream to a reaction zone comes from a high pressure recycle; and wherein each ethylene based feed stream to a reaction zone, independently, receives an output from two or more cylinders of the last compressor stage of a Hyper compressor system; and wherein the ethylene based feed stream to the first reaction zone is from 20 wt% to 60 wt% of the total ethylene based feed stream to the reactor configuration; and wherein the sum of the last two ethylene based feed streams to the reactor configuration is from 20 wt% to 80 wt% of the total ethylene based feed streams to the reactor configuration. <EOS>
