Abstract
Process for manufacturing olefin polymers, in which some of the suspension of olefin polymer particles formed in a diluent is drawn off from the polymerization reactor and diluted by means of a liquid before being sent into a hydrocyclone separator in which, on the one hand, a concentrated suspension of polymer particles and, on the other hand, a stream essentially comprising diluent are formed and separated.
