摘　　要：用元素分析、红外光谱、X射线光电子能谱、热重分析等表征在非水溶剂中以热聚合的方式合成漆酚镨高聚物(PUPr),并研究了PUPr和Na2SO3催化引发单体聚合的特性和机理。结果表明,漆酚与PrC l3形成配位键后,其侧链进一步交联成高分子化合物。其中镨原子的配位数仍未达到饱和,具有进一步接受电子的能力。在亚硫酸钠协同作用下,PUPr能催化引发甲基丙烯酸丁酯等带有给电子基团的乙烯类单体于水介质中在不除氧、无搅拌情况下进行聚合。Urushiol praseodymium polymer （PUPr）, prepared by thermo-polymerization in non-aqueous medium was characterized by elemental analysis, IR, XPS, TG, etc, which indicated that the formation of PUPr was attributed to the coordination between urushiol and PrCl3 followed by cross-linking reaction among the side chains of urushiol. Resulted from the unsaturated coordination of praseodymium, PUPr was reactive for catalyzing the polymerization of olefinic monomers such as butyl α-methacrylate in the presence of sodium sulfite.
