Abstract
A hydrogel composition is provided that includes crosslinked dextran and dextran sulfate. The hydrogel composition may be included in a matrix that includes an osmotically active material immobilized in the matrix. The hydrogel composition can be combined into superabsorbent preparations that are capable of adsorbing large amounts of water. The superabsorbent preparations have advantages in the use of absorbent materials for physiological fluids, such as diapers, incontinence products, wound dressings and the like, as well as agricultural and environmental applications. In addition, biodegradable superabsorbents of the invention can be prepared.
