Zusammenfassung:{PG,1 Improvement of the polyaryloxy and polyalkylaryloxy-phosphazenes such as those described in U.S. Pat. No. 3,853,794 is achieved by treating such polyphosphazenes with organic amines, preferably in solution. The polyphosphazenes are chemically modified as a result of such treatment and are converted from tough fibrous materials to relatively soft readily processed products.
