The　effect　of　molar　ratio　of　dual　monomers,　2-phenoxyethyl　acrylate　(POEA)　and　N-vinyl　carbazole　(NVC),　on　polymerization　efficiency　of　photopolymers　for　holographic　storage　was　investigated.　Through　monitoring　the　relative　change　of　the　double　bond　absorption　of　samples　in　FTIR　spectra　versus　exposure　time,　the　reactivity　ratio　of　two　monomers　in　solid　films　was　determined　and　the　polymerization　mechanism　was　discussed.　For　satisfying　the　requirement　of　angle-multiplexed　holographic　storage,　a　prefect　photopolymer　model　was　supposed.　Holographic　properties　of　a　series　of　samples　with　different　molar　ratio　of　dual　monomers　were　measured　and　analysed.
