In the current study, the aggregated anisotropic phase occurred in solutions prepared from acid hydrolyzed cellulose of dp 35. The higher minimum cellulose concentration for mesophase formation was observed in cellulose solutions richer in NH4SCN (see Figure 6). In these aspects, the cellulose/NH3/NH4SCN system resembles the DMAC/LiCl/cellulose system. [Pg.176]

The former prediction is now discussed. In the cellulose/NH3/NH4SCN system, the observation that the minimum cellulose concentration for mesophase formation increased with increasing NH4SCN in the solvent up to approximately 75.5%, indicates that this specific solvent composition may be regarded as a good solvent composition. [Pg.176]
