Abstract (en)

[origin: WO2011162544A2] Disclosed is a polymerization reactor for the preparation of a superabsorbent polymer, and a method for preparing a superabsorbent polymer using the same. More particularly, the polymerization reactor may evenly supply polymerization energy to both sides of a sheet-type polymer and more efficiently progress to increase productivity, and residual monomer contents may be minimized to prepare a superabsorbent polymer with excellent properties.
