  • Patent number: 10967358
    Abstract: Composite granules that contain a binder and a polymeric sorbent material for capturing aldehydes such as formaldehyde are provided. Additionally, methods of making the composite granules, methods of using the composite granules to capture aldehydes, and compositions formed by reacting the composite granules with aldehydes 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. Aldehydes can react with the nitrogen-containing groups.

    Abstract: Sorbent polymeric material suitable for capturing formaldehyde, polymeric material resulting from the capture of formaldehyde by the sorbent polymeric material, and methods for capturing formaldehyde are provided. The sorbent polymeric material has multiple aromatic rings and can be formed by initially preparing a precursor polymeric material from a polymerizable composition that contains a free-radically polymerizable spirobisindane monomer.

Each R6 is hydrogen or an alkyl. Each R7 is hydrogen or —C(?NH)—NH2. Each Q is a single bond, alkylene, or a group of formula -(Q1-NR6)x-Q2- where each Q1 is an alkylene, each Q2 is an alkylene, and x is in an integer in a range of 1 to 4.
