FIELD: polymerization processes.
SUBSTANCE: invention provides ethylene polymerization process at pressure between 1000 and 4000 bar and temperature from 140 to 320°C, which is characterized by that water is continuously or stepwise is fed into reactor so that reaction proceeds at such pressure and temperature, at which water is in supercritical state.
EFFECT: improved heat extraction and thereby increased degree of ethylene conversion.
