摘要
以硝基乙烷为原料,经过氧化硝化反应、迈克尔加成反应、酯的水解反应、脱羧溴化反应、亲核加成反应、醇解反应、酯化反应得到了3,3-二硝基丁基丙烯酸酯,并按自由基聚合机理,合成了含能粘合剂聚3,3-二硝基丁基丙烯酸酯。用FTIR、1H NMR、XRD、DSC等方法表征了聚3,3-二硝基丁基丙烯酸酯的结构和性能。结果表明,聚3,3-二硝基丁基丙烯酸酯为无定型结构,玻璃化温度38℃,在250℃下,热失重22%。
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 ℃.
