| 摘 要： | 通过两步法合成了可UV固化的超支化聚氨酯丙烯酸酯(HBUA).用SEC、FT-IR、1H-NMR和TG对HBUA进行表征,并测试了其UV固化膜的机械性能.结果表明:HBUA的分子量分布系数为2.31,丙烯酸端基改性程度为79.8%.HBUA的粘度较低有利于混合及涂布.UV固化膜具有高的硬度和良好的柔韧性.

| Abstract: | The UV-curable hyperbranched polyurethane acrylate (HBUA) with a multi-hydroxyl functional hyperbranched polyester was synthesized via a two-step procedure. The products were characterized by SEC, FT-IR, 1H-NMR and TG. The mechanical properties of UV-curing HBUA films were also investigated. It is found that the polydispersity index of HBUA is 2.31 and the endcapped degree of acrylation is 79.8%. The viscosity of HBUA is relatively low in favor of mixing and spreading. The UV-curing films exhibit high hardness and good flexibility. |
