摘　　要：合成了系列端酰肼基阴离子型水性聚氨酯,并用GPC、IR及1H-NMR分析其结构,通过其与硅烷偶联剂γ-(2,3-环氧丙氧基)丙基三甲氧基硅烷(KH 560)的室温固化反应,得到了性能优异的聚氨酯涂层。A series of water-based anionic polyurethanes with terminal hydrazide groups were synthesized and their structures were analysed by GPC, IR and ^1H-NMR. They were further cured with silane coupling agent T-（ 2,3-epoxy propoxy） propyltrimethoxysilicane （KH 560） at ambient temperature to form coatings of good performances.
