WebApr 13, 2024 · The Properties of Phosphazenes. They are a class of inorganic polymers containing nitrogen and phosphorus atoms. These compounds have a variety of properties that make them useful for a range of applications. They are generally insoluble in water, but they can be modified to be more water-soluble. They are also flammable and have a high … Webbackbone and varying molecular weight, the physical/chemical properties of phosphazene materials can be changed considerably. Many cyclic phosphazenes are either liquids or low- melting crystalline solid^.^ As molecular weight increases by either increasing the size of the substituent or the number of P-N subunit, oils and greases are formed ...
