When cellulose is phosphorylated with phosphorus oxychloride, the reactivity of the cellulose, as well as reaction time and temperature, influences the relative amounts of phosphorylated and chlorinated product formed. The swelling ability of the phosphorylated product is affected by the pretreatment received by the cellulose (i.e., prior to phosphorylation) to change its reactivity. The thermal decomposition process of phosphorylated cellulose, as indicated by differential thermal analysis, is affected also by the pretreatment received by the cellulose.
