USE OF ELECTRODIALYSIS TO REDUCE HALOGEN CONTENT IN AN AQUEOUS SOLUTION OF A NITROGEN CONTAINING EPIHALOHYDRIN-BASED RESIN, USE OF THE RESIN IN PAPER PRODUCTION

A process for reducing the content of organic and inorganic halogen in an aqueous solution of a nitrogen-containing epihalohydrin-based resin, in which process the aqueous resin solution is subjected to an electrodialysis treatment. The aqueous resin solutions obtained by the process are used as add...

Beschreibung
Zusammenfassung:	A process for reducing the content of organic and inorganic halogen in an aqueous solution of a nitrogen-containing epihalohydrin-based resin, in which process the aqueous resin solution is subjected to an electrodialysis treatment. The aqueous resin solutions obtained by the process are used as additives in the production of paper, board and paper board, in particular as wet-strength agents.
