摘要： A process for the preparation of solutions of cellulose derivatives from which formed bodies, such as fibres or films, of regenerated cellulose can be obtained by coagulation and regeneration, e.g. by wet spinning, is disclosed. The cellulose is transformed into a methylol derivative containing more than 2 units of formaldehyde per anydroglucosidic unit, which derivative is soluble in organic solvents of the class consisting of polar aprotic solvents constituted by N-substituted amides, pyridine and formamide. The methylol derivative is prepared by treating cellulose with paraformaldehyde and dimethylsulphoxide. The methylol derivative is then dissolved in one of the aforesaid solvents, preferably dimethylformamide or dimethylacetamide, to provide spinnable viscous solutions from which formed bodies can be obtained, e.g. by spinning in an aqueous alkaline bath.
