The invention relates to a process and apparatus for preparing an ethylene polymer by free radical polymerization under ultra-high pressure. The polymerization is carried out in an autoclave reactor in the presence of a free radical initiator. The autoclave reactor is characterized by having one or more elongated baffles affixed to the interior reactor wall.

A high-pressure separator with improved efficiency is provided. The separator comprises a centrifugal separator located inside of a gravity separator. The centrifugal separator has an enclosed upper portion and desirably comprises a single cylinder. The high-pressure separator is particularly suitable for use in the production of low-density polyethylene under high pressure.
