摘要： The invention relates to a hydrogel containing chemically modified proteins and polysaccharides. A method is additionally provided for producing a hydrogel from mixtures of proteins and polysaccharides. According to the invention, the proteins and polysaccharides are chemically modified in a covalent manner and chemically crosslinked in an intermolecular manner in the method. The chemically derivatized protein-polysaccharide blend (PPB for short) produced according to the invention is characterized in that the PPB forms a hydrogel in an aqueous medium. The PPB hydrogel according to the invention is characterized by a high water binding potential and a strong adhesive effect. In the field of construction chemistry for example, the PPB hydrogel according to the invention has an advantageous effect on the adhesive and sliding behavior of tiles.
