Reversible chain association/dissociation phenomenon via CO2 responsive crosslinking/decrosslinking was detected in aqueous solutions of polyallylamine (PAA). The chain association/dissociation behavior was reversible and useful in the synthesis of porous crosslinked polystyrene, which suggested potential utility in the area of CO2-responsive separable adhesives, switches and sensors.
