Abstract: A novel phosphorous-containing flame retardant was synthesized with double trimethylolpropane as raw material. The flame retardancy of the flame retardant is good due to its high molecular weight，stable loop structure，and higher thermal stability compared with common flame retardants. The effects of raw material ratio，reaction temperature and reaction time on the yield were discussed. The thermal stability of target product and its flame retardancy to different fabrics were investigated. The structures of intermediates and target product were characterized with Fourier transform infrared spectrometer. The results show that reaction effect was better when raw material ratio was 1∶3，phosphating temperature was 50℃，reaction time was 5h，and amination temperature was 75℃. And the flame retardant has obvious flame retardancy to nylon，has certain flame retardant effect to polyester and cotton，but no obvious retardancy to blending and acrylic
