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。
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 ℃,TD345 ℃) compared with PS.The solubility of PVCH is improved,i.e.it can completely dissolve in petroleum ether and cyclohexane.
