New photopolymers were designed and prepared using a photoreactive polymer binder. The holographic gratings were successfully fabricated in the photo-polymer sample by conventional optical interference method. The diffraction property from the gratings in a new photopolymer was investigated by real-time optical recording to evaluate the effect of photoreaction be between the polymer binder and the newly formed polymer. The dynamic behaviors of the diffraction. efficiency were also studied by using the photopolymers bearing photoreactive binders with different degree of substitution of the photoreactive moiety.
