    Abstract: Polymeric sorbents for reactive gases 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 polymeric sorbent has nitrogen-containing groups that are covalently attached to the polymeric sorbent. The nitrogen-containing groups include a primary amino group, a secondary amino group, a tertiary amino group, or a combination thereof. Additionally, methods of sorbing reactive gases on the polymeric sorbents and compositions resulting from the sorption of reactive gases on the polymeric sorbents are provided.

    Abstract: Polymeric sorbents for aldehydes including formaldehyde are provided. More particularly, the polymeric sorbents are a reaction product of a hydrolyzed divinylbenzene/maleic anhydride polymeric material having carboxylic acid groups with a nitrogen-containing compound having at least two primary amino groups and/or secondary amino groups. The nitrogen-containing compound is ionically attached to the hydrolyzed divinylbenzene/maleic anhydride within the polymeric sorbent and has at least one primary amino and/or secondary amino group available for reacting with an aldehyde. Additionally, methods of making the polymeric sorbents, methods of sorbing aldehydes (i.e., aldehydes that are volatile under use conditions) on the polymeric sorbents, compositions resulting from the sorption of aldehydes on the polymeric sorbents, composite granules containing the polymeric sorbents, methods of making the composite granules, and methods of sorbing aldehydes on the composite granules are provided.

    Abstract: Composite granules that contain a binder and polymeric sorbent materials for capturing reactive gases are provided. Additionally, methods of making the composite granules and methods of using the composite granules to capture reactive gases, and compositions formed by exposing the composite granules to reactive gases are provided. The polymeric sorbent material included in the composite granules is a reaction product of a divinylbenzene/maleic anhydride precursor polymeric material with a nitrogen-containing compound. This reaction results in the formation of nitrogen-containing groups that are covalently attached to the polymeric sorbent. The reactive gases undergo an acid-base reaction with the nitrogen-containing groups.
