Abstract

Polymerization of ethylene by free-radical initiation at high temperature and pressure in a stirred autoclave by continuous process is improved by means of cooling at inner wall in contact with polymerization reaction mixture and removing part of the exothermic heat of polymerization reaction by indirect heat transfer to heat exchange fluid.
