포름알데하이드를 포함하는 알데하이드용 폴리머 수착제가 제공된다. 특히, 폴리머 수착제는 다이비닐벤젠/말레산 무수물 전구체 폴리머 재료와 질소 함유 화합물의 반응 생성물이다. 질소 함유 화합물은 생성된 폴리머 수착제에 공유 결합된다. 추가로, 폴리머 수착제 상에 알데하이드를 수착하는 방법(즉, 사용 조건 하에서 휘발성인 알데하이드) 및 폴리머 수착제 상에 알데하이드를 수착하여 생성되는 조성물이 제공된다. 폴리머 수착제는 전형적으로 다공성이며, 기공 크기는 종종 메소기공 및/또는 미세기공의 범위이다. Polymeric sorbents for aldehydes including formaldehyde are provided. More particularly, the polymeric sorbents are a reaction product of a divinylbenzene/maleic anhydride precursor polymeric material with a nitrogen-containing compound. The nitrogen-containing compound is covalently attached to the resulting polymeric sorbent. Additionally, methods of sorbing aldehydes (i.e., aldehydes that are volatile under use conditions) on the polymeric sorbents and compositions resulting from the sorption of aldehydes on the polymeric sorbents are provided. The polymeric sorbents typically are porous with the pores often being in the size range of mesopores and/or micropores.
