ABSTRACT:
Cellulose is activated by penetration of the cellulose with a polar medium and mixed at a temperature at which no significant degradation occurs with an amide selected from the group consisting of dimethylacetamide, 1-methyl-2-pyrrolidinone and mixtures thereof and from 3 to 15% by weight of lithium chloride. The cellulose is then dissolved in the amide and lithium chloride in the substantial absence of any polar medium other than the amide. Shaped cellulosic products may be formed by reconstituting the cellulose in fiber, sheet or other form.
