摘　　要：通过丙烯酸甲酯和乙二醇胺的Michael加成反应,制得了AB2型单体N,N’-二羟乙基-3-氨基丙烯酸甲酯,通过添加核单体和采用"准一步法"的合成途径,制备了端羟基超支化聚(酯-胺)。通过丙烯酸对该聚合物进行改性反应,得到了端丙烯酸酯基的超支化聚合物,研究了改性聚合物与丙烯酸异冰片酯的紫外光固化涂层性能。The AB2 type monomer. N, N＇-diethylol -3 -amino methyl acrylate, was synthesized from methyl acrylate and diethanolamine by Michael addition reaction. Then hyperbranched poly（ ester-amine ） with terminal hydroxyl groups was prepared in quasi -one -step by adding the monomer. The polymer was modified with acrylic acid to obtain hyperbranched poly （ ester - amine ） s with terminal acrylate groups. The UV curing properties of sole modified poly（ ester -amine） and its mixture with isobornyl acrylate were studied.
