VERFAHREN ZUR HERSTELLUNG EINES PORÖSEN VERNETZTEN POLYSACCHARIDGELS UND SEINE VERWENDUNG ALS FILTERMEDIEN UND IN DER CHROMATOGRAPHIE |
摘要 |
A process for the production of a porous cross-linked polysaccharide gel and a gel obtainable by the following steps: a) preparing a solution or dispersion of the polysaccharide; b) adding a bifunctional cross-linking agent having one active site and one inactive site to the solution or dispersion from step a); c) reacting hydroxylgroups of the polysaccharide with the active site of the cross-linking agent; d) forming a polysaccharide gel; e) activating the inactive site of the cross-linking agent; f) reacting the activated site from step e) with hydroxylgroups of the polysaccharide gel, whereby cross-linking of the gel takes place. The cross-linked polysaccharide gel obtained can further be cross-linked by conventional methods, one or several times. |
