| 摘 要： | 靶用氘代聚合物的合成与性能研究一直是ICF领域的研究热点。采用聚苯乙烯(PS)经氢化反应制备出非氘代聚环己基乙烯(PVCH),利用傅里叶红外光谱仪、核磁共振仪和凝胶渗透色谱对PVCH结构进行了表征,表征结果与目标结构吻合良好,同时摸索出最优合成条件,并通过差式扫描量热仪和热重分析仪对其热性能进行分析。结果表明:PVCH相对于PS的玻璃化转变温度和初始分解温度都有所提高,分别达到146℃和345℃;PVCH在溶解度方面也得到改善,可以完全溶于石油醚和环己烷中。

| Abstract: | Poly(vincylcyclohexane) (PVCH) was prepared with polystyrene(PS) saturated using heterogeneous hydrogenation techniques. The structure of the synthesized polymers was characterized by means of FT-IR, 1H NMR spectroscopy and GPC, and the results show a good agreement with the proposed structure. The optimum condition for PVCH synthesis was obtained via many experiments. DSC and TG measurements show that PVCH possesses good thermal stability (Tg=146 ℃, TD>345 ℃) compared with PS. The solubility of PVCH is improved, i.e. it can completely dissolve in petroleum ether and cyclohexane. |
