Abstract (en)
[origin: WO2006000197A1] The invention relates to a method for producing molded cellulose bodies by using ionic liquids, especially 1,3-dialkylimidazolium halides, as solvents. According to said method, the cellulose is dissolved, the solution is shaped into fibers or foils/membranes, the cellulose is regenerated with the aid of a precipitation process in aqueous solutions, the solvent is separated by washing, and the molded bodies are dried.
