Abstract

Det er beskrevet en fremgangsmåte for fremstilling av aktiverte chitosaner, hvorved man omsetter et chltosan med en syre for saltdannelse og deretter fortrinnsvis med en base. Syretllsatsen og basetllsatsen som fortrinnsvis foretas ved aktiveringen gjennomføres 1 et suspens jonsmlddel som 1 stor grad forhindrer at chltosansaltene går 1 oppløsning. Som suspensjonsmldler kan det både anvendes vandige oppløsninger av uor- ganiske salter og også organiske eller vandlg-orgeinlske oppløsnlngsmldler. Det er videre beskrevet en fremgangsmåte for fremstil- ling av både vannoppløselige og også vannuoppløselige chltosanderlvater ved omsetning av de aktiverte chltosanene med reagenser som generelt er egnede for omsetningen av polysakkarider henholdsvis aminer.
