    Abstract: A continuous process for manufacturing a polyolefin resin in at least two reactors in series is described, in which: in a first polymerisation reactor, an olefin is polymerised continuously in the presence of a catalyst and a diluent to produce a first suspension comprising the diluent and polyolefin particles; at least a portion of said first suspension is transferred from the first polymerisation reactor to a second polymerisation reactor where further polymerisation takes place; a further suspension comprising diluent and polymer particles is withdrawn from the second reactor and transferred to two separators, in each of which separators a diluent-rich flow and a concentrated suspension of polyolefin particles are formed and separated, wherein the diluent-rich flow from one separator is recycled to a reactor preceding the second reactor, and the diluent-rich flow from the other separator is recycled to the second reactor. The invention enables higher separator efficiencies to be achieved.
