Abstract

PURPOSE: To obtain the titled polymer stably and continuously with prevented deposition of fine powder on the wall surface and clogging of a piping, by discharging the unreacted gas stream containing a fine powdery polymer from a vapor-phase polymerizing zone, leading the gas stream to a cyclone, collecting the fine powdery polymer, and circulating the fine powdery polymer through the polymerizing zone.
CONSTITUTION: In polymerizing an olefin in the vapor phase, a catalytic suspension prepared by preliminarily polymerizing a small amount of the olefin in the presence of a transition metallic compound catalytic component and an organometallic compound catalytic component in a separate vessel is fed from a pipe 1 through a heater 2 to gasify a liquid medium. The resultant suspension is then fed to a polymerizer 3 in which a fluidized bed 4 is formed on a perforated plate 6. The polymerization of the suspension is carried out while fluidizing the bed 4. An unreacted gas stream containing the resultant fine powdery polymer after passing through the fluidized bed 4 is then led from a pipe 7 to a cyclone 8 to collect the fine powdery polymer, which is then removed by the sucking with a sucking force from the bottom of the cyclone 8 and circulated through a vapor-phase polymerizing zone in the polymerizer 3 and polymerized.
