염기성 질소-함유 화합물을 포획하는 방법이 제공된다. 염기성 질소-함유 화합물은 설폰산-함유 중합체 재료 상에의 수착(예를 들어, 흡착)에 의해 포획된다. 설폰산-함유 중합체 재료는 자유-라디칼 중합성 스피로비스인단 단량체를 함유하는 중합성 조성물로부터 형성된다. 추가적으로, 적어도 하나의 -SOH 기를 갖는 설폰산-함유 중합체 재료와 화학식 Q의 염기성 질소-함유 화합물의 반응 생성물인 중합체 재료가 제공된다. 이러한 중합체 재료는 적어도 하나의 화학식 -SO(QH)의 기를 갖는다. A method of capturing a basic, nitrogen-containing compound is provided. The basic, nitrogen-containing compound is captured by sorption (e.g., adsorption) on a sulfonic-acid containing polymeric material. The sulfonic acid-containing polymeric material is formed from a polymerizable composition that contains a free-radically polymerizable spirobisindane monomer. Additionally, a polymeric material is provided that is a reaction product of a sulfonic acid-containing polymeric material having at least one -SO3H group and a basic, nitrogen-containing compound of formula Q. This polymeric material has at least one group of formula -SO3−(QH+).
