G. Bosscher et Jc. Vandegrampel, SYNTHESIS AND POLYMERIZATION OF -METHYL(VINYLBENZYL)TETRACHLOROCYCLOTRIPHOSPHAZENE, Journal of inorganic and organometallic polymers, 5(3), 1995, pp. 209-216
A new styrene-substituted chlorocyclotriphosphazene, gem-methyl(vinylb
enzyl) tetrachlorocyclotriphosphazene, has been prepared from vinylben
zylmagnesium chloride and hexachlorocyclotriphosphazene. The organosub
stituted chlorocyclotriphosphazene has been used in radical homo- and
copolymerization with methyl methacrylate. The reactivity ratios for t
he MMA copolymerization show a small effect of the phosphazene ring on
the olefin reactivity. All these polymers exhibit flame-retardant pro
perties.
