The invention relates to the use: - of a solution comprising at least one protic solvent, at least one monomer comprising an (alkyl)acrylic, (alkyl)acrylate or (alkyl)acrylamide group, at least one crosslinking agent comprising at least two groups chosen from (alkyl)acrylic, (alkyl)acrylate or (alkyl)acrylamide groups, at least one photopolymerization initiator and at least one agent chosen from alkali metal halides, alkali metal phosphates, alkali metal sulfates and mixtures thereof; or - of a polymer material capable of being obtained by polymerization of the solution defined above comprising a polymer resulting from the polymerization of the monomer(s) and of the crosslinking agent(s) as defined above and trapping, at the center thereof, a liquid phase comprising at least one agent as defined above; for the trapping of at least one toxic chemical agent. L'invention a trait à l'utilisation : - d'une solution comprenant au moins un solvant protique, au moins un monomère comprenant un groupe (alkyl)acrylique, (alkyl)acrylate ou (alkyl)acrylamide, au moins un agent de réticulation comprenant au moins deux groupes choisis parmi les groupes (alkyl)acrylique, (alkyl)acrylate ou (alkyl)acrylamide, au moins un amorceur de photopolymérisation et au moins un agent choisi parmi les halogénures alcalins, les phosphates alcalins, les sulfates alcalins et les mélanges de ceux-ci; ou - d'un matériau polymérique susceptible d'être obtenu par polymérisation de la solution définie ci-dessus comprenant un polymère issu de la polymérisation du ou des monomères et du ou des agents de réticulation tels que définis ci-dessus et piégeant, en son sein, une phase liquide comprenant au moins un agent tel que défini ci-dessus; pour le piégeage d'au moins un agent toxique chimique.
