Abstract
Process for manufacturing an olefin polymer composition in at least two polymerization reactors connected in series, in which the suspension of polymer in a diluant, formed in the first reactor, is sent into a hydrocyclone seperator in which, on the one hand, a stream comprising diluant and, on the other hand, a concentrated suspension of polymer particles are formed and separated. The concentrated suspension is then introduced into the subsequent polymerization reactor.
