Abstract
Official abstract text for this publication.
Flame retardant cellulose is prepared comprising cellulose fibers and an organophosphate compound bonded to the cellulose fibers. Accordingly, the bonded phosphate-functional group provides the cellulose fibers with pendant phosphate ester functionality. Numerous phosphate derivatives can be envisaged that will accomplish the intended task.
