Abstract :A novel N--P-containing soybean-oil-based fire-retardant plasticizer was synthesized using soybean oil methyl ester, 9,10-dihydro-9-oxa-phosphaphenanthrene-10-oxide insert ignore into journalissuearticles values(DOPO);, and trisinsert ignore into journalissuearticles values(2-hydroxyethyl); isocyanurate insert ignore into journalissuearticles values(THEIC);. The structure was verified by Fourier transform infrared insert ignore into journalissuearticles values(FTIR); spectrometry and nuclear magnetic resonance insert ignore into journalissuearticles values(NMR); spectroscopy. The blends were characterized by thermogravimetric analysis insert ignore into journalissuearticles values(TGA);, FTIR spectrometry, scanning electron microscopy insert ignore into journalissuearticles values(SEM);, and dynamic mechanical analysis insert ignore into journalissuearticles values(DMA);. TGA showed that the thermal stability of the blends were acceptable. DMA indicated that the plasticizer had good plasticity for PVC. The limiting oxygen index insert ignore into journalissuearticles values(LOI); of the blends ranged from 21.3 to 29.6. The flammability and thermal stability of PVC/THEIC-DOPO-ESOME was better than that of PVC/TCPP.
