| Abstract: | Melaminephosphate( MP) was prepared by reaction of melamine with phosphoric acid using transition metal heteropolyacid as catalyst and deionized water as solvent. Melamine polyphosphate ( MPP) was synthesized by condensation of MP under multi-temperature calcination stage in the box of the atmosphere in the furnace. The structure was characterized by 31 P NMR, IR and elemental analy-sis, and the thermal property and carbon residue property were investigated by TG. The results showed that the temperature with 1 wt% and 5 wt% loss were 372. 1 ℃ and 382. 7 ℃, respectively, the car-bon residue rate at 700 ℃ was 37 . 36%. |
