摘要
以聚-5-乙烯四唑(PVT)和硫酸二甲酯为起始原料,经甲基化反应制得聚N-甲基-5-乙烯四唑(PM VT),产率为97.36%。采用元素分析、IR、NM R、D SC-TG和感度测试等方法对PM VT进行了结构和性能表征,初步评估其热力学性能和安全性能,研究结果显示:PM VT放气分解温度(291.75℃)高于原料PVT(238℃),机械感度与PVT相当。
Poly（N-methyl-5-vinyltetrazole）s（PMVT） was synthesized with poly（5-vinyltetrazole）（PVT） and dimethyl sulfate as primary materials with yield of up to 97.36%.The structure of PMVT was identified by IR and NMR.Further,the thermodynamic behavior of PMVT was studied by DSC-TG analysis,while the safety performance of PMVT was evaluated by the mechanical sensitivity testing.Results show that the temprature of thermal decomposition of the pendanted tetrazole group of PMVT is higher than that of PVT,and the sensitivity of PMVT is closed to that of PVT.
