Abstract
A continuous polymerization reactor for super absorbent polymer is disclosed. The continuous polymerization reactor includes a cylindrical body; a discharge part with a diameter decreasing downward, positioned at a lower part of the body; an inlet positioned at an upper part of and connected to the body, into which a monomer composition is introduced; an outlet positioned at a lower part of the discharge part, from which hydrogel polymer is discharged; and a discharge valve opening or closing the outlet, wherein a ratio (H1/D1) of a sum (H1) of a height of the body and a height of the discharge part to a diameter (D1) of the body is 2 to 4. In addition, a continuous polymerization reaction system comprising the continuous polymerization reactor is also disclosed.
