摘要
在惯性约束聚变(ICF)靶材应用领域,氘代聚合物一直占据着重要位置。本文在氘代苯乙烯(D8,98%)中加入质量分数为其0.4%的引发剂,采用本体聚合方法聚合全氘代聚苯乙烯(D8,DPS),反应温度为70℃,反应时间为72 h,用傅里叶变换红外光谱仪、核磁共振仪对DPS的结构进行表征,综合测试结果表明产物为DPS。采用差式扫描量热仪和热重分析仪分析DPS的热性能,表明DPS的玻璃化转变温度为105℃,5%失重温度为380℃,热性能较好,满足ICF试验使用要求。
In the field of application for the inertial confinement fusion （1CF） target material, Deuterium generation of polymer had been occupying an important position. In this paper, Deuterated styrene, with its 4 % AIBN, used the ontology polymerization to synthesize deuterium generation of polystyrene （DPS）. The reaction temperature was 70 ℃ and the reaction time was 72 h. And studied the structure of DPS by the fourier transform infrared spectrometer （FT/IR） and nuclear magnetic resonance （NMR）. The test results showed that the comprehensive the product was DPS. The thermal properties of DPS were analyzed by differential scanning calorimeter and thermogravimetric analyzer. DSC and TG measurements show that DPS possesses good thermal stability （Tg = 105 ℃ Td〉380℃）.
