An open and closed case : Polymerization of microemulsions stabilized by surfactants based on ionic liquids leads to cross‐linked polymer gels which can be transformed into porous polymers by anion exchange of the ionic liquid moiety. These porous polymers can be converted back into polymer gels by immersion in organic solvents. Subsequent immersion of these gels in water then affords the porous polymers once more (see scheme).
