Flame retardant cellulose acetate is prepared comprising cellulose acetate flakes and an organophosphate compound bonded to the cellulose acetate flakes. Accordingly, the bonded phosphate-functional group provides the cellulose acetate flakes with pendant phosphate ester functionality. Numerous phosphate derivatives can be envisaged that will accomplish the intended task.
