摘　　要：乙二胺与丙烯酰氯于-5～5℃在二氯甲烷中反应生成N-丙烯酰基-乙二胺,再与肉桂酰氯在室温反应得N-丙烯酰基-N′-肉桂酰基乙二胺,产率88%,用IR,1HNMR和13CNMR对其结构进行了表征。以过硫酸铵为引发剂,该单体在水中聚合生成带有肉桂酰基的聚丙烯酰胺衍生物,聚合温度50℃,反应时间12h,产率82%,用IR和1HNMR对聚合物结构进行了表征。该聚合物在紫外光照射下进行光交联反应,生成不溶于丙酮的网状结构体型聚合物。N-Acryloylethylenediamine was synthesized by reacting ethylenediamine with acryloyl chloride at -5 -5 ℃ in dichloromethane. Then cinnamoyl chloride was added into the reaction system and the reaction was carried out at ambient temperature to prepare N-acryloyl-N＇- cinnamoylethylenediamine in 88% yield, which was characterized by IR,^1HNMR and ^13CNMR. Cinnamoylated polyacrylamide derivative was prepared by in 82% yield polymerization of the monomer in water with ammonium persulfate as initiator at 50 ℃ for 12 h, and the polymer was characterized by IR and ^1HNMR. The photocrosslink reaction occurred when the polymer was dissolved in acetone and irradiated by ultraviolet light, and the network structured three-dimensional polymer insoluble in acetone was obtained.
