Abstract
Cellulose is dissolved in an oxide of a tertiary amine, e.g., the oxide of trimethylamine, triethylamine, tripropylamine, monomethyldiethylamine, dimethyl - monoethylamine, or dimethyl - cyclohexylamine, or pyridine oxide. The solutions may be precipitated as threads or films by means of water, alcohol, or dilute acid. Specification 480,358 is referred to.
