Abstract (en)
[origin: WO2012107362A1] Method for processing cellulose carbamate, in which cellulose carbamate is mixed with a swelling agent or solvent. Through exertion of pressure and optionally increase of temperature, the mixture is brought into a desired shape; the amount of cellulose carbamate exceeds the maximum solubility of the cellulose carbamate in the swelling agent or solvent by a factor of 1.5 to 6 for the prevailing physical conditions of temperature, pressure and available dissolution time.
