| 摘 要： | 采用聚苯乙烯(PS)催化氘化技术，在使苯环被氘化饱和的基础上，成功地制备出了部分氘化的聚环己基乙烯（D-PVCH，C8H8D6）。用傅里叶红外光谱仪、核磁共振仪对D-PVCH的结构进行了表征，结果表明与目标产物吻合，即苯环被氘饱和转化为环己基，氘代率为41.5%。采用差式扫描量热仪和热重分析仪分析了D-PVCH的热性能，结果表明D-PVCH的玻璃化转变温度为125 ℃，5%失重温度为403 ℃。另外，D-PVCH可溶于常见溶剂，如石油醚、环己烷和甲苯等。与PS相比，D-PVCH具有较好的热稳定性和良好的溶解性能。

| Abstract: | Deuterated poly(vincylcyclohexane) (D-PVCH, C8H8D6) was successfully prepared via deuterated catalytic technology of polystyrene(PS). The structure of D-PVCH was characterized by FT-IR and 1HNMR spectroscopy, and the results show good agreement with the proposed structure and the deuterated ratio is 41.5%. DSC and TG analyses of the D-PVCH show that D-PVCH possesses good thermal stability (glass transition temperature of 125 ℃, 5% weight loss temperature of 403 ℃). Additionally, D-PVCH dissolves in common solvents such as petroleum ether, cyclohexane and toluene at room temperature. Compared with PS, D-PVCH possesses better thermal stability and improved solubility. |
