摘要：
The present invention relates to a method for a superabsorbent polymer. The preparation method controls the time from the addition of a foaming agent to the initiation of a polymerization reaction, thereby forming an appropriate pore structure in a superabsorbent polymer. The superabsorbent polymer produced through the preparation method can exhibit a remarkably improved absorption rate while exhibiting excellent absorption performance.
