초록

폴리카보네이트 폴리올, MDI 및 N-methyldiethanolamine(MDEA)로부터 폴리카보네이트형 우레탄 수지를 합성하고, MDEA의 4차 암모늄염화 반응에 의해서 양이온성 폴리카보네이트 우레탄 수지를 제조하였다. 우레탄 연쇄내 이온기의 함량이 증가함에 따라 인장강도 탄성율은 현저하게 증가되었으나 내가수분해성등은 저하되는 경향을 표시하였다. 에탄올/물 혼합용액 분리실험에서 양이온성 폴리카보네이트형 우레탄 막의 선택도는 20 정도였으며, 이때의 분리기구는 carrier mediated transport mechanism을 따른 것으로 생각된다.

Cationic polycarbonate type polyurethane was prepared from the quaternization reaction of N-methyldi-ethanolamine(MDEA) in urethane backbone which was obtained from the reaction of polycarbonate polyol, MDI and MDEA(chain exetender). Tensile strength and modulus of the cationic urethane resins were increased sharply with increasing the ionic content in urethane backbone. But hydrolysis resistance was decreased with increasing ionic contents. The selectivity of the cationic polycabonate urethane membrane for water/ethanol separation by pervaporation was about 20. The carrier mediated transport mechanism was considered the most probable separation mechanism for these membranes.
