Abstract (en)

[origin: WO2019120529A1] The invention relates to a method for producing cellulose carbamate by reacting cellulose and urea at elevated temperature in an organic reaction medium. The products resulting from this method are characterized by good solubility in sodium hydroxide solution and are particularly suitable for producing cellulose mouldings, for example regenerated cellulose fibres, films and beads.
