| abstract |
A novel biodegradable, water resistant polymer material is disclosed which can be produced with defined material properties, in particular as foils, films, strips, compounds, moulded bodies or the like, and which is essentially composed of products of the cross-linking reaction of polysaccharides and/or polypeptides whose hydroxyl, amino, imino, thiol and/or carboxyl groups are at least partially derived by non-radical reaction with agents which include groups that can be cross-linked in a separate process step following derivation. |
