Abstract: The invention relates to a process for the preparation of a multimodal polyolefin polymer in a first polymerization reactor and a second polymerization reactor connected in series, wherein a first polyolefin polymer is prepared in the first polymerization reactor in suspension in the presence of hydrogen and a second polyolefin polymer is prepared in the second polymerization reactor in the presence of a lower concentration of hydrogen than in the first polymerization reactor, the process comprising: a) withdrawing a suspension of solid polyolefin particles in a suspension medium from the first polymerization reactor, wherein the suspension medium comprises hydrogen and a hydrocarbon mixture having an initial boiling point of at least 50° C. and a final boiling point of at most 120° C.; b) feeding the suspension to a flash drum having a pressure controlled by a vacuum pump, wherein the pressure of the flash drum is less than 0.1 MPa; c) vaporizing a part of the suspension medium in the flash drum to obtain a hydrogen-depleted suspension and d) withdrawing the hydrogen-depleted suspension from the flash drum and feeding it to the second polymerization reactor.
