SE PRESENTAN MACROESTRUCTURAS ABSORBENTES, POROSAS, QUE CON EL CONTACTO CON LIQUIDOS COMO POR EJEMPLO AGUA O EXUDADOS DEL CUERPO (POR EJ. ORINA), SE HINCHAN Y EMBEBEN TALES LIQUIDOS, Y SON UTILES EN ARTICULOS ABSORBENTES COMO POR EJEMPLO PAÑALES, PAÑALES DE INCONTINENCIA, Y COMPRESAS SANITARIAS. ESTAS MACROESTRUCTURAS POROSAS CONSTAN DE PARTICULAS ABSORBENTES ENLAZADAS EN SU SUPERFICIE CON ADUCTOS DE AMINO-EPICLORIHIDRIN CATIONICOS, PREFERIBLEMENTE POLIMERICOS. Porous, absorbent macrostructures that, upon contacting liquids such as water or body exudates (e.g., urine), swell and imbibe such liquids, and are useful in absorbent articles such as diapers, adult incontinence pads, and sanitary napkins are disclosed. These porous macrostructures comprise bonded absorbent particles that are surface crosslinked with cationic, preferably polymeric, amino-epichlorohydrin adducts.
