| 摘 要： | 以3-溴甲基-3-甲基氧杂环丁烷(BrMMO)为单体,按阳离子开环聚合机理,先合成出3-溴甲基-3-甲基氧杂环丁烷均聚物(PBrMMO),接着在偶极非质子溶剂中对其进行叠氮化,最终合成出含能黏合剂3-叠氮甲基-3-甲基氧杂环丁烷均聚物(PAMMO)。着重研究了BrMMO聚合过程中催化剂用量和反应体系温度对聚合的影响,确定出BrMMO聚合的最佳条件为:n(BF3.OEt2):n(BDO)=0.50:1.00,0℃下加入单体,通过红外光谱确定出叠氮化反应的完成时间。用红外光谱(IR)、核磁共振(1H-NMR)、热重分析(TGA)和差示扫描量热法(DSC)对产品进行了表征。

Synthesis of Energetic Binder PAMMO by Indirect Approach |
| |
| Abstract: | Firstly, 3-bromomethyl-3-methyloxetane homopolymer(PBrMMO) was synthesized by the cationic ring-opening polymerization with 3-bromomethyl-3-methyloxetane(BrMMO) as monomer. Secondly, PBrMMO and 3N awNere dissolved in dipolar aprotic solvent for PBrMMO aziding. Lastly, the energetic binder 3-azidomethyl-3-methyloxetane homopolymer(PAMMO) was synthesized. The effects of catalyst concentration and reaction system temperature on polymerization in BrMMO polymerization were studied emphatically. The optimal conditions of BrMMO polymerization are as followns:(B F3.OEt2):n(BDO)=0.50:1.00, BrMMO is added in the reaction system at 0℃. The aziding reaction time is identified by IR spectra. The product is characterized by IR, 1H-NMR, TGA and DSC. |
