We suggested new photopolymer systems using polyacrylic acid (PAA), polyitaconic acid (PICA), and the photosensitive polymer (PP) as binders. The photochemical reaction of the photosensitive polymer binder and acrylamide monomers was studied by virtue of infrared spectroscopy. The holographic grating was elaborated by conventional optical interference method. The dynamic behaviors of the grating formation were studied with the change of exposure intensity. We observed the variation of the diffraction efficiency during post UVexposure. The surface topographical change of photopolymer layer was also observed by atomic force microscope (AFM).
