摘　　要：用二丁基二月桂酸锡作催化剂,由甲基丙烯酸甲酯和N,N-二甲基乙二胺合成了一种新型功能单体甲基丙烯酰胺乙基二甲基胺(MAEDA)。最佳合成条件为:原料N,N-二甲基乙二胺和甲基丙烯酸甲酯的摩尔配比为1:2,催化剂二丁基二月桂酸锡的加入量为料液量的2%,在95～100℃间反应4 h,产物收率可达94%。产物经红外光谱、H NMR、C NMR和元素分析等进行了表征。A novel functional monomer, methyl acrylamide ethyl dimethyl amine （MAEDA） was synthesized from methyl methacrylate and N, N-dimethyl ethylenediamine in the presence of tin dibutyl dilaurate as catalyst. The optimum conditions were found as follows., molar ratio of N, N-dimethyl ethylenediamine to methyl methacrylate 1 ： 2, 2% catalyst in the feed solution, reaction temperature 95 -100 ℃ and reaction time 4 h. The yield reached above 94% under the above conditions. The product was characterized by IR spectrum, 1H NMR,C NMR and elemental analysis.
