Abstract
A process for monitoring the polymerization of ethylene or ethylene and comonomers in the presence of free-radical polymerization initiator at pressures in the range of from 160 MPa to 350 MPa and temperatures in the range of from 100° C. to 350° C. in a tubular reactor with one or more reaction zones, which is equipped with cooling jackets for cooling the tubular reactor with a cooling medium, comprising a step of measuring as process parameters the temperature profile and the pressure of the reaction medium and the flow and temperature profile of the cooling medium along the reactor.
