以乙烯脲（ EU）为新型扩链剂，异佛尔酮二异氰酸酯（ IPDI）、二羟甲基丙酸（ DMPA）为硬段，聚四氢呋喃醚二醇（PTMG1000）为软段，先合成水性聚氨酯脲（PU-EU）；然后利用互穿聚合物网络（ LTPN）改性的方法将丙烯酸丁酯（ BA）、甲基丙烯酸缩水甘油醚（ GMA）在PU-EU乳液中共聚，利用乙二胺（ EDA）与其交联，制备出具有核-壳结构的水性聚氨酯脲-丙烯酸酯复合乳液（ PU-EU/PA）。结果表明，PU-EU/PA复合乳液具有良好的耐热性、力学性能和较高的硬度，形成了具有化学交联的核-壳互穿网络结构聚合物。

The waterborne polyurethane urea( PU-EU) was syntherized by taking ethylene urea ( EU) as a no-vel chain extender, and isophorone diisocyanate (IPDI), dimethylol propionic acid (DMPA) as hard segment, while polytetrahydrofuran glycol ( PTMG1000 ) as soft segments. The PU-EU was modified using butyl acrylate ( BA) , glycidyl methacrylate ( GMA) by linear interpenetrating polymer network modification method. Using ethyl-enediamine ( EDA) as crosslink agent, waterborne polyurethane urea-acrylate ( PU-EU/PA) hybrid emulsion was prepared. The results showed that PU-EU/PA hybrid emulsion had excellent heat resistance, mechanical properties and high pencil hardness. The core-shell interpenetrating polymer network structure by chemical crosslinking was formed.
