(Vinyloxy)chlorocyclotriphosphazenes

摘要

The reaction of the lithium enolate of acetaldehyde, LiOCHCH2, with hexachlorocyclotriphosphazene, N3P3Cl6, lead to the series of (vinyloxy)chlorocyclotriphosphazenes, N3P3Cl6-n(OCH=CH2)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.
