Polyurethane and polymethacrylate bearing an aminonitroazobenzene were synthesized for fabricating the diffraction grating on the film surface. Two beam coupling method was employed for fabricating the diffraction grating. The dynamics of diffraction grating was studied in term of the variation of the diffraction efficiency. The long-term stabilities of the diffraction efficiency was also investigated and compared in two polymers.
