METHOD FOR PREPARING SUPERABSORBENT POLYMER |
| 摘要 |
The present invention relates to a method for preparing a superabsorbent polymer. The method for preparing a superabsorbent according to the present invention includes the steps of: polymerizing a monomer composition into a superabsorbent polymer in a polymerization reactor; grinding the obtained superabsorbent polymer; and hydrolyzing the fine particles generated during the process and reusing the same for the monomer composition. |
