ABSTRACT:
Solutions of cellulose in hydrazine are formed by dissolving cellulose therein. The cellulose solutions formed may be utilized for the preparation of fibers, films, foams or other cellulose fabricated articles. Alternatively, the dissolution of cellulose in hydrazine may be employed as a means for the direct extraction of cellulose from lignocellulosic materials without the necessity of pulping operations.
