Abstract
Disclosed is a continuous bulk polymerization reactor comprising a cylindrical reaction vessel elongated in the direction of the reacting fluid and a shaft installed within the reaction vessel. A plurality of flow of double helical-ribbon agitators are attached to the shaft in such a way that they face in the same direction, and a plurality of baffles having a relative open area of 5 to 40% based on the cross-sectional area of the internal space of the reaction vessel, are disposed between any adjacent ones of the agitators. Thus the formation of stagnant fluid pockets is avoided and excellent piston flow properties are achieved.
