This invention discloses a category of cyanuramide derivate which has perfluoro-chain hydrocarbon and its preparation. Cyanuramide derivate which has perfluoro-chain hydrocarbon is produced by condensation reaction of acyl fluoride monomer which has perfluoro-chain hydrocarbon and cyanuramide. This derivate can be used as high-grade paint, flame retardant, special material assistant, active oxidation stabilizing agent of high-grade lubricating oil, its structural formula is formula I,x,p,z=0,1,2;And x+y=2,p+q=2,e+z=2 but x,p,z does not equal 2 at the same time, among them Rf is formula II, n=0-10. |
