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.

Erfindungsgemäß wird ein Hydrogel enthaltend chemisch modifizierte Polysaccharide und Proteine bereitgestellt. Es wird darüberhinaus ein Verfahren bereitgestellt, um aus Gemischen von Polysacchariden und Proteinen ein Hydrogel herzustellen. Erfindungsgemäß werden durch das Verfahren die Polysaccharide und Proteine chemisch kovalent modifiziert und intermolekular chemisch vernetzt. Der erfindungsgemäß hergestellte, chemisch derivatisierte Polysaccharid-Protein-Blend (abgekürzt "PPB") ist dadurch gekennzeichnet, dass er in wässrigem Medium ein Hydrogel ausbildet. Das erfindungsgemäße PPB-Hydrogel ist charakterisiert durch ein hohes Wasserbindungspotential und eine hohe Klebewirkung. Beispielsweise in der Bauchemie wirkt sich das erfindungsgemäße PPB-Hydrogel vorteilhaft auf das Klebe- und Abrutschverhalten von Fliesen aus.
