Study on the Emulsion Polymerization of Hydroxyethyl Acrylate-Acrylate-Acrylonitrile Copolymer (PHMA) and Isophorone Diisocyanate (IPDI) for the Encapsulation of Nitramine Filler HMX and Its Mechanical Properties for Energetic Composites .The optimum reaction conditions were obtained by XPS test on the adsorption and polymerization of prepolymer on the surface of HMX.The mechanical properties of the composites were tested by static mechanical properties.XPS tests showed that the emulsion polymerization was more effective than the solution polymerization Which is conducive to the cross-linking reaction on HMX surface.The emulsion polymerization-coating conditions are the best reaction temperature 45 ℃, reaction time 12 0 min, the best coating quality when the mass of prepolymer is 0 .15 ~ 0. . The coated HMX was used in the composites and the tensile strength of the material increased by 21.3%, indicating that the crosslinked coating formed on the surface of the nitramine HMX crystal played an interface enhancing effect
