ABSTRACT:
Products having high absorbency for use in absorbent dressings and the like are prepared by precipitating a water-insoluble but water-swellable superabsorbent polymer onto the surface of a long fiber cellulose from an aqueous slurry and drying the resulting coated fibers by dehydration with a water-miscible nonsolvent for the polymer.
