Abstract
Single phase gels for preventing the formation of surgical adhesions are disclosed. The gels are prepared by reacting an aqueous solution of a polyanionic polysaccharide, such as hyaluronic acid or carboxymethyl cellulose, with divinyl sulfone, to form a gel, the solution is neutralized, and a solid is precipitated from the solution. The solid can be redissolved in water to form a gel having properties which can be modified to suit a particular application.
