Abstract
The multifunctional cation exchangers, sulfonated polypropylene-g-(acrylic acid/styrene) [PP-g-(AAc/Sty)] were synthesized by the irradiational grafting of AAc and Sty onto PP staple fabric with electron beam accelerator and its subsequent sulfonation. The highest degree of grafting obtained was 190% at a monomer mixture of 30 vol% AAc : 70 vol% Sty and a solvent mixture of 30 vol% water : 70 vol% methanol and the degree of grafting decreased with an increase of the AAc content in the monomer mixture at constant solvent content. Maximum ion exchange capacity of the copolymer was 4.6 meq/g. The Li+ adsorption ability of the copolymer synthesized in the study was the best among PP-g-AAc, sulfonated PP-g-Sty, and sulfonated PP-g-(AAc/Sty).

E-beam 전조사법을 이용하여 아크릴산과 스틸렌 단량체를 폴리프로필렌 섬유에 그라프트 반응시켜 PP-g-(AAc/Sty) 공중합체를 합성하고 술폰화 반응시켜 다관능성 섬유상 양이온 교환체를 합성하였다. 합성체의 그라프트율은 물과 메탄올 혼합비가 30:70vol% 일 때 190%로 최대이었으며 혼합용매의 조성비가 일정할 때 아크릴산 단량체의 양이 증가할수록 그라프트율은 감소하였다. 또한 이온교환체의 이온교환용량은 4.6 meq/g이었으며, 술폰화 이온교환체와 아크릴산 이온교환체의 리튬이온에 대한 흡착량을 비교한 결과 본 연구에서 합성한 이온교환체의 흡착성이 우수한 것으로 나타났다.
