摘　　要：利用乙二胺和丙烯腈的亲核加成反应合成了一种有机多腈N,N,N′,N′-四(2-氰基乙基)乙二胺;以Raney Ni对N,N,N′,N′-四(2-氰基乙基)乙二胺进行催化加氢,得到N,N,N′,N′-四(3-氨基丙基)乙二胺;再将该化合物与精二聚酸进行缩聚反应,制得新型支爪形聚酰胺。采用红外、核磁、质谱、热分析的方法对支爪形聚酰胺的结构进行表征。A organic polynitrile N,N,N′,N′-tetra（2-nitrilethyl）ethylenediamine was synthesized by the nucleophilic additive reaction of ethylenediamine and acrylonitrile.The N,N,N′,N′-tetra（3-aminopropyl）ethylenediamine was synthesized by the hydrogenation of N,N,N′,N′-tetra（2-nitrilethyl）ethylenediamine in the presence of catalyst Ni.Then a new branch-claw type polyamide was synthesized by condensation with N,N,N′,N′-tetra（3-aminopropyl）ethylenediamine and dimmer fatty acid.The molecular structure of the product has been characterized by means infrared spectrum（IR）,nuclear magnetic resonance（NMR）,elemental analysis,electros pray ionization mass spectrometry（ES-MS）and thermogravimetric-differential scanning calorimeter（TG-DSC）.
