Porous, absorbent macrostructures that, upon contacting liquids such as wate r or body exudates (e.g., urine), swell and im- bibe such liquids, and are useful in absorbent articles such as diapers, adu lt incontinence pads, and sanitary napkins are dis- closed. These porous macrostructures comprise bonded absorbent particles tha t are surface crosslinked with cationic, preferably polymeric, amino-epichlorohydrin adducts.
