资源简介：
A process for dissolving oxidized cellulose and forming a plurality of oxidized cellulose particles. The process comprises contacting the oxidized cellulose with a solvent under an inert atmosphere to form a swelled oxidized cellulose， adjusting the swelled oxidized cellulose to a first temperature of about 115° C to 145° C， contacting the swelled cellulose with salt to form an oxidized cellulose solution， adjusting the solution to a second temperature from about 90° C to about 120° C and contacting the oxidized cellulose solution with at least one multivalent cation selected from cations of calcium， barium， zinc， magnesium， chromium， platinum， or iron to form a plurality of oxidized cellulose particles.
