1. A process comprising:
contacting an oxidized cellulose with a solvent under an inert atmosphere to form a swelled oxidized cellulose; adjusting the swelled oxidized cellulose to a first temperature; contacting the swelled oxidized cellulose with a salt under the inert atmosphere to form an oxidized cellulose solution; and adjusting the oxidized cellulose solution to a second temperature that is lower than the first temperature; and contacting the oxidized cellulose solution with at least one neutralizing agent to form a plurality of oxidized cellulose particles. |
