ABSTRACT:
A method for reconstituting superabsorbent polymer fines which comprises the following steps: wetting the superabsorbent polymer fines with an aqueous solution sufficient to form an amorphous gel of the fines, grinding the gel, and drying the ground gel product; wherein the improvement is characterized by the addition of an aqueous solution containing a persulfate salt.
