Abstract

1,147,019. Olefin polymerization. SOLVAY & CIE. 5 March, 1968 [20 March, 1967], No. 10658/68. Heading C3P. A process for withdrawing an olefin polymer suspension from a reactor in which the polymerization of olefins is carried out continuously under low pressure in an inert diluent and in the presence of a catalyst, comprises withdrawing a substantial amount of the crude polymer suspension from the polymerization reactor and pouring it into a decanting zone, withdrawing a portion of the polymer enriched broth at least corresponding to the production of the polymer in the reactor and recycling to the polymerization reactor the slightly concentrated polymer containing liquid which is extracted from the decanting zone, through a recycling conduit. At least one of the constituents of the reaction medium is introduced into the slightly concentrated polymer containing liquid which has been extracted from the decanting zone and is being recycled. The constituents preferably added in this way are the monomer, diluent and chain transfer agent, the catalyst being introduced directly into the reactor. The proportions of polymer enriched broth and slightly concentrated polymer containing liquid leaving the decanting zone may be adjusted by means of a regulating valve mounted in the recycling conduit. In the Figure, an apparatus suitable for carrying out the process is shown. Crude polymer suspension is removed from the reactor 1 via the tube 3 and conveyed into the decanter 6. A portion of the concentrated broth discharged from the decanter is conveyed back to the reactor 1 by means of the conduit 7, while the other portion is withdrawn through the valve 9. The slightly concentrated polymer containing suspension is conveyed from the separator to the reactor via the conduit 10 and regulating valve 11. The tube 12 allows the introduction of reaction medium constituents. In an example, a hexane solution of ethylene is polymerized in the presence of a catalyst constituted by the product of the reaction between Mg(OH)Cl and TiCl 4 , the catalyst being activated by triisobutyl aluminium.
