Injecting a first feed comprising a chain transfer agent system (CTA system) and ethylene into a first autoclave reactor zone operating at polymerization conditions to produce a first zone reaction product, the CTA system of the first reactor zone having a transfer activity Z1; and B. (1) Transferring at least part of the first zone reaction product to a second reactor zone selected from a second autoclave reactor zone or a tubular reactor zone and operating at polymerization conditions, and, optionally, (2) freshly injecting, a second feed into the second reactor zone to produce a second zone reaction product, with the proviso that at least one of the first reactor zone product and the freshly injected feed comprises a CTA system with a transfer activity of Z2; and with the proviso that the ratio of Z1:Z2 is greater than 1.

The invention also provides a high pressure polymerization process to form an ethylene-based polymer, the process comprising at least the following steps: feeding ethylene to a first reaction zone and to one or more subsequent reaction zones, and wherein 100 weight percent of the total amount of fresh ethylene fed to the polymerization process is fed to the first reaction zone, and wherein the “total amount of ethylene fed to the polymerization process” derives from at least one fresh ethylene stream and at least one recycled ethylene stream, and wherein the at least one recycled ethylene stream comprises at least one chain transfer agent and/or comprises at greater than, or equal to, 1 weight %, based on total amount of components in recycled ethylene stream, of one or more non-ethylene components and/or CTA(s); and wherein the inlet stream to each reaction zone comprises less than, or equal to, 5 weight ppm oxygen, based on the total weight of mass flows fed to the reaction zone.
