FOAM MATERIALS

An absorbent foam material which comprises a solid, cross-linked form of an anionic polymer (e.g. an alginate) and fibres or other cation contributing polymeric particulates which have donated appropriate cations for effecting cross-linking of the anionic polymer. Methods of producing the foam mater...

Beschreibung
Zusammenfassung:	An absorbent foam material which comprises a solid, cross-linked form of an anionic polymer (e.g. an alginate) and fibres or other cation contributing polymeric particulates which have donated appropriate cations for effecting cross-linking of the anionic polymer. Methods of producing the foam material are also disclosed. La présente invention porte sur une mousse absorbante comprenant une forme réticulée solide de polymère anionique (ex. une alginate), des fibres ou d'autres particules polymériques à contribution cationique, ayant donné des cations appropriés pour effectuer une réticulation du polymère anionique. L'invention porte également sur des procédés de production de mousse.
