MONOPHASE PROCESS FOR THE POLYMERIZATION OF ETHYLENE IN THE PRESENCE OF WATER

摘要

1. A process for polymerizing ethylene in the presence of at least one free radical initiator, in at least one reactor having at least one reaction zone, at a pressure between 1000 and 3000 bar and at a temperature between 180 degrees and 300 degrees C, characterized in that said polymerization is effected in the presence of water at a concentration higher than or equal to 1% by weight and lower than or equal to the saturation concentration of water in ethylene at the temperature of said reaction zone.
