The present invention provides polymeric adsorbents for reactive gases. More specifically, the polymeric adsorbent is the reaction product of a divinylbenzene/maleic anhydride precursor polymeric material and a nitrogen-containing compound. The polymeric adsorbent has nitrogen-containing groups covalently attached to the polymeric adsorbent. The nitrogen-containing group includes a primary amino group, a secondary amino group, a tertiary amino group, or a combination thereof. Alternatively, the present invention provides a method of adsorbing a reactive gas on the polymeric adsorbent and a composition obtained by adsorbing a reactive gas on the polymeric adsorbent. |
