Phosphorus-Containing Polymers—The Phosphazenes

摘要: Rubber-like networks made from polyphosphazene chains were reported as early 1897 by Stokes.1 One particular compound, poly(dichlorophosphazene), came to be known “inorganic rubber” because of the similarity many its mechanical properties those natural rubber. Thermal decomposition polymer did not commence until about 300°C, but rapid hydrolysis inorganic salts in moist air precluded any practical applications. Much effort was devoted overcoming this problem synthesis analogous polymers without halogen groups, or attempting total replacement groups itself. The attempts frustrated insoluble, intractable nature materials produced and consequent difficulties chemical modification processing. first report preparation a linear, high-molecular-weight which completely soluble benzene, Allcock Kugel 1965.2 chloro could replaced others yield products good hydrolytic stability.
