| 中文摘要 | 本研究中,一系列之己內醯胺/十二內醯胺共聚物利用單體鑄模方法合成。其中1,6-己二異氰酸塩為起始劑,氫化鈉為催化劑。該共聚物之物性,如熱性質,收縮率,吸水性及機械性分別針對十二內醯胺的含量予以評估。結果證明收縮率,吸水性及耐衝擊強度可被改善,而其他機械性,如抗張強度及模數,曲折模數及熱安定性有降低現象。 |
| 英文摘要 | A family of ε-caprolactam (HL₅) and ω-dodecalactam (HL□) copolymer was synthesized through the monomer casting technique using hexamethylene diisocynate (HDI) as the initiator adn sodium hydride (NaH) as the catalyst. Physical properties, such as thermal properties, shrinkage, water absorption and mechanical properties, were evaluated with respect to the HL□ composition. Improvements of shrinkage, water absorption and impact strength were achieved, however, losses of the tensile strength, tensile modulus, flexural modulus and the thermal stability were observed. |
