    Abstract:   在本研究論文中嘗試使用一種有別於傳統的非異氰酸鹽之合成法來合成聚胺酯化合物(PU)。在常壓的實驗條件下先使用環氧樹脂與二氧化碳進行加成反應合成出環碳酸酯,再使用不同的長鏈雙胺化合物(Jeffamine)與環碳酸酯化合物進行開環反應,使之經由開環加成聚合反應而形成聚胺酯化合物,並對其討論聚合反應後的性質變化。並且藉由麥可加成反應將壓克力官能基導入聚胺酯主鏈段的末端上,即可以得到一新型且紫外光可架橋之非異氰酸鹽合成法的聚胺酯寡聚物(UV-PU)。而在本實驗流程中所使用的溶劑為環保型溶劑,如乳酸乙酯,且同時使用一具有可回收特性的催化劑,如溴化鋰等。故本實驗在合成聚胺酯的過程可以被歸納為符合節能減碳與對環境友善的綠色製程。
      經由此種製程之PU樹脂紫外光照射成膜後具親水性環保型聚胺酯樹脂薄膜,在物理性質方面,以膠含量、吸水率、對水損失率、吸乙醇率、對乙醇損失率及接觸角進行分析比較;在光學性質方面,利用掃描式電子顯微鏡與薄膜外觀進行分析;在熱性質分析方面,以熱重分析儀與動態機械分析加以探討;最後並藉由AATCC的標準水洗測試來證實本材料具有的長效性親水特性。
      In this research, a new UV-curable hydrophilic PU resin was obtained through a green, nonisocyanate, three-reaction process: (1) cyclic carbonate (BCC or PPG-DCE) compounds are prepared by inserting carbon dioxide into epoxy resins (DGEBA or PPG-DGE) at atmospheric pressure; (2) amino-terminated hydrophilic PUs (NH2-PU) prepolymer are obtained through the ring-opening polymerization of BCC and PPG-DCE utilizing di-functional or tri-functional amino hydrophilic (polyether) compounds such as Jeffamine D-2000 or T-3000; (3) UV-curable acrylate-PU oligomer (UV-PU) are obtained as adducts from the Michael addition of NH2-PU to multi-acrylate-terminated compounds, 3-acryloyloxy-2-hydroxypropyl methacrylate (AHM). We used as ethyl lactate (EL) as a green solvent and a recyclable catalyst as lithium bromide. This is an energy saving and environmental friendly green process toward PU formation.
      In this research, UV-PU films are compared to the difference of their properties. Finally all the data of each resulted polyurethane resins with different formulations are evaluated and discussed in this report.
