Abstract

The Parent Patent describes substd. phosphazenes for fire-proofing cellulosic, e.g. viscose filaments and fabrics which are prepd. by reacting a mixt. of phospho-nitrile halides, with an aromatic alcohol or alkanol, so that halogen atoms are replaced by aryloxy or alkoxy groups. In this addition the reaction mixt. contains phospho-nitrile chlorides of formula (PNCl2)n (where n is at least 3), 65-95% of this prod. consisting of cyclic cpds., and propanol, and the mixt. of propoxylated phosphazenes has an average mol. wt. of 900-1600, esp. 1000-15000, and a viscosity of 1400-4800 esp. 1500-4500 cP at 25 degrees C. Gives faster, more reproducible reaction and better fireproofing action.
