Abstract

Det beskrives nye blandinger bestående av semiinterpenetrerende nettverk av fornettede, vannoppløselige derivater av basiske polysakkarider og en ikke-fornettet komponent som er et anionisk polysakkarid. Det beskrives metoder for fremstilling av slike blandinger. Fortrinnsvis er det basiske polysakkarid kitosan eller et derivat derav og det anioniske polysakkarid hyaluronsyre. Blandingene kan omdannes til geler eller filmer og således finne anvendelse innen et vidt spektrum av medisinske anvendelser på områdene dermatologi, plastisk kirurgi, urologi og ortopedi.
