ABSTRACT:
The invention is concerned with a cellulose sponge which may be produced by mixing a solution of cellulose in an aqueous tertiary amine-oxide with a pore forming agent and a sponging agent and subsequently exposing it to conditions which cause a decomposition of the sponging agent and a foaming of the cellulose solution, whereafter the foamed cellulose is contacted with water to precipitate the cellulose.
