Abstract
Sulfonated poly(phenylene sulfide) (S-PPS) was prepared by the reaction of poly(phenylene sulfide) (PPS) with sulfur trioxide. The sulfonation was confirmed by the high intensity band of the SO3H group at 1140∼1280 cm-1. The ion exchange capacity of soluble S-PPS and insoluble S-PPS was 3.231 meq/g and 2.866 meq/g, respectively. The ion exchange capacity and IR absorbance of SO3H group of S-PPS were decreased as the curing temperature was increased. In addition, the adsorption of S-PPS for metal ions and the formation of crosslinkage between neighbouring phenyl rings of S-PPS were discussed.

Sulfonated polyphenylene sulfide (S-PPS)는 poly(phenylene) sulfide (PPS)를 액체 SO3로 술폰화하여 합성하였으며 1140∼1280cm-1의 영역에서 방향족 술폰산의 술폰산기에 의한 강한 흡수대에 의하여 확인되었다. 수용성 S-PPS와 불용성 S-PPS의 이온교환용량은 각각 3.231 meq/g과 2.866 meq/g이었다. 불용성 S-PPS는 경화온도가 증가할수록 이온교환용량과 술폰산기의 IR흡광도는 감소하였다. 그리고 금속이온 흡착능과 인접 페닐기간의 가교결합 형성에 관하여 논의하였다.

Keywords: ion exchange capacity; sulfonated poly(phenylene sulfide)
