| 中文摘要 | 本研究利用4,4’-雙苯基甲苯與苯雙酣反應中添加雙醇(如聚丙二醇和正丁二醇)在雙甲基醯胺當溶濟中進行反應,以增加聚醯亞胺的柔軟性,本研究並利用紅外線光譜儀來鑑定確認聚(醯亞胺─烏拉坦)共聚合物的特性。聚(醯亞胺─烏拉坦)共聚合物並加以測定其機械性質與熱安定性,實驗結果發現,利用烏拉坦確實可大幅提升聚醯亞胺的柔軟性,然而卻降低其熱安定性。 |
| 英文摘要 | A study of increasing the flexibility of the polypyromelliticimide resin was carried out by the reaction of 4,4'-diphenylmethane diisocyanate with pyromellitic dianhydride and diols, such as polypropylglycol and butane diol, in dimethylformamide as solvent. The IR spectra is used to confirm the characteristic of the poly(imide-urethane) copolymers. Copolymers are characterized by mechanical strength and thermal characteristics. The results indicated that have greatest increase of flexibility, however, decreased of thermal stability. |
