摘　　要：Holographic parameters and photobleaching kinetics of the photopolymers with five different amine photoinitiators are studied. The maximum values of diffraction efficiency, photobleaching coefficient and quantum yield follow the sequence： Triethanolamine （TEA）〉 Diethanolamine （DEA）〉 Ethanolamine （EA）〉 Triethylamine （TETN）〉 Diethylamine （DETN）. The holographic capabilities of photopolymer performances are determined by the number of functional groups in the amine molecular structure. There is an optimum proportion of the photoinitiator, the photosensitizer and the monomer in the test of holographic parameters with different amine concentrations. The maximum diffraction efficiency is 59.26／%, sensitivity is 1.72／times 10^{ - 3}~cm^{2}/mJ, and the maximum refractive modulation index is 4.64／times 10^{ - 4}.Holographic parameters and photobleaching kinetics of the photopolymers with five different amine photoinitiators are studied.
