ABSTRACT:
A solution containing cellulose dissolved in a mixture of a tertiary amine N-oxide solvent for cellulose and a compound which increases the rate of dissolution of cellulose in the solvent such as a tertiary amine or other compound which increases the pH of the solvent, a process for making such a solution and a process for making shaped articles therefrom are provided. The solvent dissolves cellulose at a faster rate and at a lower temperature than a solvent consisting of the same tertiary amine N-oxide.
