Polyphenylene thioether sulfonate(PPTS) derivatives were prepared by sulfonating poly[methyl(4-phenylthio) phenylsulfonium] trifluoromethane sulfonate with fuming sulfuric acid. The sulfonation was confirmed by the presence of a high intensity band at 1190 cm^-1 due to the SO₃H group in arylene sulfonic acid. The ion exchange capacity of soluble PPTS(K-form) and PPTS(K-form) cured at 340℃ was 3.71 meq/g and 2.31 meq/g, respectively. The ion exchange capacity and IR absorbance at 1190 cm^-1 of PPTS derivatives were decreased as the curing temperature was increased. The temperature for weight loss of 10 percentage (Td^10%) by the TGA was also increased. In addition, the formation of crosslinkage between neighbouring phenyl rings of PPTS was discussed.

Polyphenylene thioether sulfonate(PPTS) 유도체는 poly[methyl(4-phenylthio)phenylsulfonium]trifluoromethane sulfonate를 발연황~산으로 술폰화하여 합성하였으며 술폰화는 1190cm_-1에서 방향족 술폰산의 술폰기에 의한 강한 흡수대에 의하여 확인되었다. 수용성 PPTS(K-form)과 340℃에서 ~경화된 PPTS(K-「orts)의 이온교환용량은 가가 3.71 meq/g 및 2.31 meq/g이었다. PPTS는 경화온도가 증가할수록 이온교환용량과 술폰산기의 IR흡광도는 감소하고 TGA분석에서 10% 중량감소의 온도(Td_10%)는 증가하였다. 이외에 PPTS의 인접페닐기~간의 가교 형성에 관하여 논의하였다.
