Vinyloxy)Chlorocyclotri Phosphazenes.

Abstract : The reaction of the lithium enolate of acetaldehyde, LiOCHCH2, with hexachlorocyclotriphosphazene, N3P3CL6, lead to the series of (vinyloxy)chlorocyclotri phosphazenes, N3P3CL6-n(OCH double bond CH2)n(n = 1-6). The nongeminal pathway is favored. These material undergo homopolymerization reaction and can be copolymerized with a wide variety of organic monomers. The resulting polymeric systems incorporate certain properties such as fire retardancy and are chemically bonded to the polymer rather than an additive.
