Abstract
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.
