Superabsorbent polymer particles, consisting of crosslinked poly(itaconic acid), have been surface-crosslinked using photochemical reaction. Surface crosslinking is required for many applications of superabsorbent polymers, such as disposable diapers, to control the flow and absorption of liquids in the gel bed. Photo-induced surface crosslinking has been achieved using UV irradiation in the presence of potassium persulfate. The photochemical crosslinking exhibited improved properties, such as absorbency under load and permeability, on the superabsorbent polymer particles. |
