Abstract

본 발명은 강산성 양이온교환수지의 제조방법에 관한 것으로서, 더욱 상세하게는 가교된 스티렌계 구상입자를 팽윤제의 존재하에서 열처리한 후 무수 황상으로 슬폰화하여 균열이 없고 기계적 강도 및 사이클 강도가 우수한 강산성 양이온교환수지 제조방법에 관한 것이다.The present invention relates to a method for producing a strongly acidic cation exchange resin, and more particularly, the cross-linked styrene-based spherical particles are heat-treated in the presence of a swelling agent, and then sponified into anhydrous sulfur to provide no cracking and excellent mechanical and cycle strengths. It relates to a cation exchange resin production method.
