摘要註:	環氧樹脂(epoxy resin)為應用非常廣泛的熱固性樹脂，但耐衝擊性能差，無法全面滿足工程上的要求。本研究以聚脂肪二酸(dimer fatty acid)和聚醚二胺(polyetherdiamine)行聚縮合反應，製備出醚醯胺化聚脂肪二酸之增韌改質劑，然後加入環氧樹脂中，調配成90/10、80/20、70/30、60/40 (環氧樹脂/增韌改質劑重量比)，藉由開環加成反應，使增韌改質劑以共價鍵結方式導入環氧樹脂分子結構中。實驗結果發現，硬化後環氧樹脂表面硬度、抗拉強度與抗拉模數均隨著增韌改質劑的增加而下降，抗衝擊強度與韌性則隨著增韌改質劑增加而上升，特別是在增韌改質劑添加量達到40 wt%時，增韌效果最為明顯，且未發現有相分離現象。 Epoxy resin is a widely used thermosetting resin but has poor impact resistance in some applications. In this study, carboxyl-terminated poly(ether-amide) was prepared by condensation reactions of a commercialized dicarboxylic acid and a commercialized poly(ether diamine) and was used as a toughening agent. The so-prepared toughening agent was then added into epoxy resin to have four different weight ratios of epoxy resin/toughening agent including 90/10, 80/20, 70/30, and 60/40.Upon curing at elevated temperatures, the toughening agent can be covalently incorporated into the epoxy resin via ring-opening reactions of the epoxide groups. The results found that the surface hardness, tensile strength, and Young’s modulus decreased with increasing contents of the toughening agent; the toughness and impact strength, however, increased with increasing contents of the toughening agent. In particular, the epoxy resin containing 40 wt% toughening agent exhibited the highest toughening effect without phase separations.
