Abstract

Process for the removal of a suspension of olefinic polymers from a reactor in which the polymerization of the olefins at low pressure in an inert diluent in the presence of a polymerization catalyst is carried out continuously, a process consisting in removing a substantial amount of the crude polymer suspension from the polymerization reactor, and in pouring it into a settling zone, in removing on the one hand broth enriched with polymer of which at least a part corresponds to the polymer production of the reactor, and on the other hand, in recirculate to the polymerization reactor the liquid diluted with polymer extracted from the decanter.
