Zusammenfassung:Bio-based nylon 6-morpholinone random copolymers were prepared by the anionic ring opening polymerization of ${\varepsilon}$-caprolactam and morpholinone, both of which were prepared from lysine and glucose, respectively. From this work, a new biomass based nylon 6 with improved hydrophilicity was prepared. Optimizing the polymerization condition, copolymer with a viscosity-average molecular weight of 30000 g/mol was prepared, with a yield of 80%. It was possible to improve the hydrophilicity of nylon 6 by its copolymerization with morpholinone. The prepared nylon 6-morpholinone random copolymers were then characterized using several analytical methods such as DSC, TGA, XRD, viscosity measurement with U-shaped glass capillary viscometer and contact angle measurement. 라이신과 글루코오스에서부터 제조된 카프로락탐과 모폴리논을 음이온 개환중합법을 이용하여 나일론 6-모폴리논 랜덤 공중합체를 합성함으로써 바이오매스 기반의 새로운 나일론을 제조할 수 있었으며 또한 친수성이 향상된 나일론 6을 제조할 수 있었다. 중합 조건을 적절하게 조절함으로써, 점도평균분자량 30000 g/mol과 수율 80%의 공중합체를 제조할 수 있었다. 모폴리논을 공중합 단량체로 사용함으로써 나일론 6의 친수성을 높게 향상시킬 수 있었다. 제조된 나일론 6-모폴리논 랜덤공중합체를 시차주사 열량계(DSC), 열중량 분석기(TGA), X-선 회절분석기(XRD), 점도계, 접촉각 측정기와 같은 분석방법으로 그 특성을 분석하였다.
