Abstract
A process for producing a polysaccharide sponge comprises the steps of (A) freezing a photoreactive polysaccharide solution, and (B) irradiating the frozen photoreactive polysaccharide solution with light to crosslink the photoreactive polysaccharide, thereby obtaining the polysaccharide sponge. The process includes simplified steps requiring no removal of solvent, and has such an advantage that impurities are easily removed therefrom.
