PURPOSE: To obtain a vertical agitator capable of forming a high-viscosity high molecular polymer in a high-viscosity soln. state.
CONSTITUTION: An agitating shaft 2 is inserted from the upper part of a vertical vessel main body 1, and a spiral impeller 4 is extended from both ends of an impeller-distribution supporting rod 3 to the lower part of the main body 1 while keeping a fixed gap between it and the inner face of the main body 1. A thin sheet 5 of 4 to 30mm is fixed to the upper face of the impeller 4 by welding 6, etc., to control the gap to ≤10mm. In the impeller 4 and thin sheet 5, the peripheral end face is notched at an angle of 30-80°, chamfered and retreated so that the gap is gradually widened in the thickness direction from the front in the rotating direction toward the rear.
