Abstract
Continuous process for manufacturing a polyolefin resin in at least two polymerization reactors connected in series, in which the polymer suspensions leaving the reactors are transferred into hydrocyclone separators in which a flow comprising diluent and polymer particles, on the one hand, and a concentrated suspension of polymer particles, on the other hand, are formed and separated. The flows comprising the polymer particles are recycled into the first polymerization reactor.
