ABSTRACT:
The reaction of the lithium enolate of acetaldehyde, LiOCHCH.sub.2, with achlorocyclotriphosphazene, N.sub.3 P.sub.3 Cl.sub.6, lead to the series of (vinyloxy)chlorocyclotriphosphazenes, N.sub.3 P.sub.3 Cl.sub.6-n (OCH.dbd.CH.sub.2).sub.n (n=1-6). The nongeminal pathway is favored. These materials 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.
