Abstract
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.
