This to prepare a first solid material impregnated serving it - even in the preparation of a solution of cellulose and the product

摘要

P cellulose is placed in suspension in an amine oxide), water and, optionally, a liquid organic solvent of the cellulose, until absorption of the liquid mixture of cellulose, at a temperature at which the - latter does not dissolve removed, optionally, the liquid organic solvent, and there is obtained in the solid residue, a cellulosic product containing the amine oxide, and a small proportion of moisture, which can be converted into a solution of cellulose by simple heating. / p & & p & the solution of cellulose obtained can - even be formed by fibers, films, etc, according to the usual techniques. / p
