【摘要】采用发散法合成了以乙二胺为核心的0.5~4.0代聚酰胺-胺(PAMAM0.5~4.0)树状聚合物。通过M ichael加成反应,用甲基丙烯酰氧基乙基三甲基氯化铵(DMC)对4.0代聚酰胺-胺(PAMAM4.0G)树状聚合物分子外围末端基进行修饰改性,制备了一种PAMAM4.0G-DMC新型阳离子树状聚合物。并用傅里叶变换红外光谱(FTIR)、核磁共振(NMR)方法对其结构进行表征。FTIR和NMR表征结果显示,合成的产物为改性的阳离子树状聚合物。絮凝脱水性能实验结果表明,改性后的阳离子树状聚合物具有良好的絮凝脱水性能。更多还原

【Abstract】 A series of polyamide-amine（PAMAM）dendrimers were synthesized by divergence method.PAMAM（4.0）G dendrimer was modified to polyamide-amine-methylacryloyloxyethyl trimethylammonium chloride（PAMAM（4.0）G-DMC）cationic dendrimer by using methylacryloyloxyethyl trimethylammonium chloride as modifier in Michael addition reaction.PAMAM（4.0）G-DMC cationic dendrimer was characterized by means of FTIR,¹H NMR and ¹³C NMR.By FTIR,it was confirmed that modified product was PAMAM（4.0）G-DMC cationic dendrimer,which had excellent performances in flocculating and dewatering.更多还原
