The Preparation of Quaternary Ammonium Polysulfone and its Permeation Behavior (I) -Preparation of Quaternary Ammonium Polysulfone-
양이온성의 quaternary ammonium polysulfone인 AMPS는 2단계 과정을 통하여 제조하였다. 먼저, 폴리술폰을 chloromethyl methyl ether와 촉매로 ZnO를 사용하여 chloromethylation반응으로 CMPS를 제조하는 단계와 준비된 CMPS에 triethylamine을 반응시켜 quaternary ammonium기를 도입시키는 amination 단계로 이루어 진다.
This paper was to investigate the preparation of quaternary ammonium polysulfone. The aminated polysullone (AMPS) as quaternary ammonium polysulfone was synthesized by two-step process. The first step involves the preparation of chloromethylated polysulfone (CMPS) which was produced by the introducion of chloromethyl group into polysulfone using chloromethyl methyl ether as a chloromethylation agent and zinc oxide as a catalyst. The second step, amination of CMPS was to give rise to AMPS using triethylamine.
