Abstract:
1. An odor-absorbing superabsorbing composition, comprising: i a post-crosslinked water-absorbing polymer structure having an average particle size in the range of about 515 μm to about 850 μm; and ii an odor binder comprising as components with R1 as a C X as not present or a double bond system comprising in a range from 1 to about 5 double bonds; M as a charged or uncharged metal; m in a range from 1 to about 15; n in a range from 1 to about 5; o in a range from 1 to about 4, wherein said odor binder is brought into contact with the surface of the post-crosslinked water-absorbing polymer structure after surface crosslinking such that the penetration depth of said odor binder into said surface of the post-crosslinked water-absorbing polymer structure is less than 2% of the diameter of the water-absorbing polymer structure wherein the odor-absorbing superabsorbing composition has an absorption against pressure of 0.7 psi (AAP(0.7 psi)) of from 21 g/g to 30 g/g.
