Abstract
PURPOSE: To make it possible to economically and stably produce a polymer having a suitable particle size distribution, by constructing the lower curved portion of a cylindrical reaction vessel from a perforated plate in the horizontal agitated floor type apparatus for vapor-phase polymerization of olefins.
CONSTITUTION: In the vapor-phase olefin polymerization apparatus of the horizontal agitated floor type, the lower curved portion of a cylindrical vessel 1 is constructed from a perforated plate 2, and an olefin feed chamber 3 whose upper confining member is the perforated plate 2 is provided under the perforated plate so that material olefin gases may be introduced through the perforated plate 2. Next, the polymerization is carried out in such a manner that the material olefins in gas form and, if necessary, hydrogen are introduced continuously into the body of the polymerization tank through the perforated plate from the feed chamber; a catalyst is introduced from a conduit 6 and agitation is made with an agitator 4. This method can prevent formation of hot spots during polymerization and as a consequence prevents formation of blocked polymers.
