More Information
Summary:Super-absorbing polymeric networks of cross-linked polyaspartates are produced from cross-linked polysuccinimide. Super-absorbing polymeric networks are produced in a single reaction vessel by cross-linking polysuccinimide with at least one organic polyamine cross-linking agent in the presence of at least one nitrogenous base. The reaction is carried out in an aqueous reaction mixture to produce a polymeric network of cross-linked polyaspartate.
