3,3-Dinitrobutyl acrylate was prepared from 3,3-dinitro-1-butanol and acrylic acid through direct esterification,which was obtained by the reaction of the oxidative-nitration,Michael addition,hydrolyzation,decarboxylative-bromating,nucleophilic addition and alcoholysis using nitroethane as starting materials. The energetic binder poly(3,3-dinitrobutyl acrylate) was synthesized by the free radical polymerization of 3,3-dinitrobutyl acrylate in ethyl acetate by using azobisiosbutyronitrile as initiator. The structures and properties of poly(3,3-dinitrobutyl acrylate) were also characterized by FTIR,¹H NMR,XRD,TG-DTA and DSC. Results show that poly(3,3-dinitrobutyl acrylate) is amorphous,and its glass state temperature is 38 ℃,and its mass loss is 22% at 250 ℃.
