1. A process comprising:
forming a mixture by contacting an oxidized cellulose with a solvent to form a swelled oxidized cellulose;
adjusting the mixture to a first temperature;
contacting the swelled oxidized cellulose with a salt to form an oxidized cellulose solution; and
adjusting the oxidized cellulose solution to a second temperature lower than the first temperature, wherein dissolved oxidized cellulose of the oxidized cellulose solution retains from about 80% to about 120% of a degree of oxidation of the oxidized cellulose prior to dissolution or from about 80% to about 120% of a molecular weight of the oxidized cellulose prior to dissolution.
