摘要：

The novel arborescent monomolecular P-N intumescent flame retardant hexalis-(4-(5,5-dimehtyl-1,3-dioxaphospho-rinanyl-2-oxy-phosphate-ester-phenoxy))-cyclotriphosphazene (VI) was synthesized via hexachlorotriphosphazene, 4-methoxyphenol, neopentyl alcohol and phosphous oxychloride by a three step reaction and its structure was identified and studied by FT-IR, H-1 NMR and MS analyses. The termogravimetry showed that the novel flame retardant had high thermal stability and excellent char-forming ability. The beginning temperature of the compound VI decomposition was 270 degrees C and the char yield was about 45.2% at 600 degrees C in N-2. The results demonstrated that the novel arborescent P-N intumescent flame retardant was effective on the flame retardancy of epoxy resin.
