    Abstract: Among other things, a process for producing an agglomerated superabsorbent polymer particle and an agglomerated superabsorbent polymer particle are disclosed. The process comprises the steps of: (A) bringing superabsorbent polymer fine particles having at least about 40 wt. %, a particle size of less than about 150 μm into contact with a fluid comprising to more than about 10 wt. % a cross-linkable, uncrosslinked polymer based on polymerized, ethylenically unsaturated, acid group-bearing monomers or salts thereof; and (B) cross-linking the uncrosslinked polymer by heating the superabsorbent polymer fine particles and the fluid to a temperature from about 20 to about 300° C., so that the cross-linkable, uncrosslinked polymer at least partially crosslinks.
