The aim of this study is to research the process of paranitroaniline grafting 1

8一naphthalene imidesynthesis. The nucleophilic replace mechanism of 1

8一naphthalene imide grafted on to polyphosphazene is exam-fined

and the principle of Nitroaniline coupled with 1，8一naphthalimide polyphosphazene is outlined. The idea ofmicrowave method of measurement is to analyze the synthetic conditions of coupling process by calculating the pro-ductivity. The ultraviolet spectrum results show that conjugated double bond absorption peaks of the nitrobenzeneand azo in 350一360 nm. Infrared spectrum results show that vibration absorption peak of -N=N-azon 1594 cmin 1594 cm一} and the absorption peak of C-Nn1143cmgroups1.TheresultsshowstheticproducttheabsorptionpeakofNOZthat paranitroaniline grafted 1
