PREPARATION OF CELLULOSE AMINOMETHANATE ABSTRACT OF THE DISCLOSURE An improvement to the process for synthesizing cellulose aminomethanate is disclosed which comprises slurring cellulose in low concentrations of aqueous caustic solutions, in the presence of urea, and steeping the slurried mixture, at from about 2°C to about -15°C, for a time sufficient to permit swelling of the cellulose and uniform distribution of the urea. Cellulose aminomethanate manufactured from product prepared in accord with this process, has a uniform distribution of aminomethanate throughout the cellulose at the molecular level and comprises a suitable product for manufacturing sausage casing.
