To overcome the incompatible problem of ammonnium dinitramide(ADN) and the isocyanates curing agents, the curing coating research of spherical ADN particles were carried out usinng glycidyl azide polymer(GAP)/ bis-propargyl-succinate(BPS) crosslinked polymers as a coating material via 1, 3 dipolar cycloaddition reaction.The surface element composition and hygroscopicity of the coated ADN-prills were investigated by scanning electron microscopy with energy dispersive spectrometer (EDS) and dynamic hygroscopic analytical method respectively.Results show that compared with the GAP/hexamethylene diisocyanate biuret curing agent (N-100) crosslinked polymers, the GAP/BPS crosslinked polymers exhibited better compatibility and coating effect with ADN, and the saturated hygroscopicity of coated ADN is only 0.78%.
