Abstract

1,248,951. Fluidized bed polymerization. UNION CARBIDE CORP. 21 Aug., 1968 [21 Aug., 1967 (2)], No. 39950/68. Heading C3P. Olefins are continuously polymerized in a fluidized bed by simultaneously (a) contacting a gaseous stream containing the monomer(s) with a polyhydrocarbyl aluminium oxide mixed with a transition metal compound in a polymerization zone comprising a fluidized bed of formed and forming polymer particles at a mass gas flow rate sufficient to maintain complete fluidization and at a temperature below the sintering temperature of the solid polymer particles, (b) withdrawing from said polymerization zone a small portion of the fluidized bed as discrete particles in suspension with a portion of the gaseous stream, (c) withdrawing the unreacted portion of said gaseous stream from the polymerization zone, (d) cooling said unreacted gaseous stream to remove heat of reaction, and (e) recycling the cooled gaseous stream to the polymerization zone below the base of the fluidized bed at a velocity sufficient to maintain fluidization. In the examples, ethylene or an ethylene-propylene mixture are polymerized using a polyisobutylaluminium oxide-chromium-2-ethylhexanoate catalyst on a silica or polyethylene support.
