Book Description
This program of research has been directed toward the development of new synthesis of polyphosphazenes, particularly those with alkyl and/or aryl substituents, via the elimination of substituted silanes from N-silylphosphinimines. The synthesis and characterization of both the new polymers and their precursors has been investigated. (Author).

Book Description
This research under ARO sponsorship has been directed toward the synthesis, characterization, structural isomerization, and thermal decomposition reactions of new silicon-nitrogen-phosphorus compounds. Some of these compounds undergo smooth decomposition when heated to afford phosphazenes, oligomeric materials of general formula (NPRR')n.

Book Description
The project involves a detailed study of the synthesis, characterization, and reactivity of silicon-nitrogen-phosphorus compounds, some of which are useful precursors to an important class of inorganic polymers known as polyphosphazenes. Our results include the successful development of a new, general, and direct method for the synthesis of such polymers including poly(dimethyl-phosphazene), (Me2PN)n. Thus, we report here the synthesis of a variety of new phosphazenes including several homopolymers, copolymers, crosslinked polymers, and transition metal containing polymers. The latter and many other new types of phosphazenes are now readily accessible by a recently discovered anion formation reaction of the polymer precursors.

Book Description
Many small-molecule Si-N-P compounds of appropriate design can function as precursors to various oligomeric and polymeric P-N systems. For example, poly(dialkylphosphazenes), (R2PN)n, are readily obtained via the thermal condensation-polymerization of certain N-silylphosphinimines, Me3SiN=P(X)R2. In addition, novel 3-coordinate phosphorus-V compounds including the bis(imino)-phosphoranes, RP(=NSiMe3)2, can potentially lead to new polymers of formula (RPN) sub n, the phosphorus analogs of electrically conducting (SN) sub n. The synthesis of polyphosphazenes and their precursors and the synthesis of potential precursors to (RPN) sub n are discussed.
