Studies and Properties of Coordination Polymer of Electropolyurushiol and Praseodymium Chloride

通过电化学方法合成的聚合漆酚 (EPU) ,与氯化镨作用生成聚合漆酚 镨配合物膜。采用原子发射光谱、红外光谱、荧光光谱、差热 热重分析、X光电子能谱和动态机械热分析等手段进行表征。探讨其结构与耐热性质。证明了螯合物中存在Pr3+和EPU的配位作用 ,并引起进一步交联 ,因而难溶于绝大多数有机溶剂 ,同时玻璃化转变温度和耐热性能均得到提高。

The coordination polymer (EPU Pr 3+ ) was fromed by the reaction of praseodymium chloride with electropolyurushiol polymerization (EPU). The structure and properties of the coordination polymer were characterized by AES, FT IR, fluorescence, TG DTA, XPS and DMTA. It shows that there was a certain coordination between praseodymium and electropolyurushiol in the chelate and the cross link was formed. Therefore the polymer is insoluble in most organic solvents, the glass transition temperature increases and heat resistance is enhanced considerably.
