摘要 以丙烯酸偕二硝基丙酯(DNPA)为单体,偶氮二异丁腈为引发剂,甲苯为溶剂,按自由基聚合机理,合成了含能粘合剂聚丙烯酸偕二硝基丙酯(PDNPA)。讨论了引发剂用量和反应温度对聚合反应的影响。采用FTIR、1HNMR、UV、DSC等方法研究了聚丙烯酸偕二硝基丙酯的结构和性能。结果表明,增加引发剂用量使聚合物的分子量降低,在80℃的反应温度下、2h内获得60%的单体转化率。聚丙烯酸偕二硝基丙酯的热分解温度为252.8℃,是较稳定的聚合物。 The energetic binder poly （2,2-dinitropropyl acrylate） （PDNPA） was synthesized by the free radical polymerization of 2,2-dinitropropyl acrylate in toluene with azobisiosbutyronitrile as initiator,and were characterized by FTIR, 1HNMR ,UV and DSC. The effects of initiator concentration and temperature on polymerization were investigated. Results show that the average molecular weight of the polymer decreases and molecular weight distribution （MWD） becomes narrow as increasing initiator concentration. Monomer is with 60% conversion obtained at 80℃ within 2 hours. The thermal decomposition temperature of PDNPA is 252.8℃.
