Patent ID: 8829066

Claim:
A polymerization reactor for producing a super absorbent polymer, which comprises: a reaction unit; a monomer composition supply unit being connected to the reaction unit and supplying a monomer composition solution containing a monomer, a photoinitiator, and a solvent; an agitating shaft extended in the reaction unit from one end of the reaction unit connected to the monomer composition supply unit to the other end of the reaction unit; a plurality of agitating blades installed around the agitating shaft; and a light irradiation unit providing light to the monomer composition solution supplied from the monomer composition supply unit, wherein the light irradiation unit is overlapped with 1-40% of a total length of the agitating shaft, wherein the light irradiation unit comprises a first light irradiation unit located between the monomer composition supply unit and the agitating shaft.
