MODIFIED PHOSPHAZENE FIRE RETARDANT

摘要

Flame retardants are prepared by reacting partially and fully or substantially fully hydrocarbyloxylated phosphazenes. They may be used as flame retardants for cellulose fibers, filaments, filamentary articles and films. For rayon or other regenerated cellulose the materials may be incorporated into the cellulose by adding to viscose and shaping, coagulating and regenerating a filament.
