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.
