| titleOfInvention | Method of rapidly determining the mfr in the high-pressure polymerization of ethylene |
| abstract | Method of determining the melt mass flow rate of an ethylene polymer in the polymerization of ethylene or of ethylene with further comonomers, which is carried out at temperatures of from 140°C to 350°C and pressures of from 40 MPa to 350 MPa in a reactor to form the ethylene polymer and the ethylene polymer is subsequently cooled in a heat exchanger, which comprises: a) establishment of a correlation between the thermal conductivity of the ethylene polymer in the heat exchanger and the melt mass flow rate of the ethylene polymer, with the individual measurements each being carried out at an essentially constant melt mass flow rate, b) measurement of the thermal conductivity of an ethylene polymer in the heat exchanger c) calculation of the melt mass flow rate from the thermal conductivity measured in b) and the correlation established in a). |
