Abstract:	本研究利用聚醚二胺寡聚物與二酸單體進行共聚耐隆之合成，並添加少量三官能基單體，改善分子鏈間之回彈性，其中聚醚二胺寡聚物分子量約為1000gmol-1，二酸單體為己二酸，三官能基單體為二乙基三胺(DETA)。實驗結果顯示，透過聚醚二胺寡聚物提供高分子良好的延展性及彈性，並透過三官能基單體增加分子鏈運動較自由之非晶區，達到分子間的彈性提升，共聚高分子耐隆斷裂點伸長率(%)達350%。在後段紡絲製程上，使用Side-by-Side並列纖維構造，使用共聚合之彈性耐隆與常規耐隆並列，可使織物伸長回復率達90%。 In this study, the nylon copolymer was prepared by copolymerization reaction using polyetherdiamine and diacid, in addition add small amount of tri-functional compound to improve the resilience between molecular chains in which the molecular weight of polyetherdiamine is about 1000gmol-1, the diacid is adipic acid , and the tri-functional compound is diethylenetriamine (DETA). The result showed that the polyetherdiamine providing good ductility, malleability and elasticity in nylon copolymer. Through the tri-functional compound can let copolymer increase amorphous region for molecular chains movement to enhance the intermolecular flexibility. The nylon copolymer elongation at break is up to 350%. In the melting spinning process, using Side-by-Side fiber structure by nylon copolymer and nylon, can make the recovery of elongation up to 90%.
