Abstract
In this study, poly(arylene ether sulfone) (PAES) having thermal stability and excellent mechanical properties was synthesized to be useful for the matrix of anion exchange resin. 1°-Aminated poly(arylene ether sulfone) (1°-APAES) was prepared by reduction reaction after lithiation of PAES. Then 3°-APAES was prepared by alkylation of the amine group of 1°-APAES. The structures of PAES and APAESs were confirmed with FT-IR and H1-NMR spectroscopy. Also, thermal properties of the resins were characterized by DSC and TG analysis. The introduction of amine groups in PAES resulted in the increase of glass transition temperature and decrease of initial thermal degradation temperature. The ion exchange capacities of 1°-APAES and 3°-APAES were 1.19 and 1.45 meq/g, respectively.

열 안정성과 우수한 기계적 성질을 갖는 poly(arylene ether sulfone) (PAES)을 음이온교환수지의 지지체로 이용하였다. 1°-Aminated poly(arylene ether sulfone) (1°-APAES)은 PAES을 리튬화한 후 환원 반응시켜 제조하였고, 3°-APAES은 1°-APAES의 아민기를 알킬화 반응시켜 제조하였다. PAES와APAES들의 구조는 FT-IR과 H1-NMR으로 확인하였고, 열적 특성은 DSC와 TG 분석을 통하여 조사하였다. PAES에 아민기가 도입됨에 따라 Tg는 증가하였고, 초기 열분해 온도는 감소하였다.1°-APAES과 3°-APAES의 이온교환용량은 각각 1.19와 1.45 meq/g 이었다.

Keywords: anion exchanger; thermostable ion exchanger; poly(arylene ether sulfone); amination
