Chemical weapons trapped the swell way

Hypercrosslinked polymers absorb deadly agents

UK researchers have shown that polymers can absorb chemical warfare agents. When dried, the densely crosslinked polystyrene networks can swell to accommodate organic molecules. They can therefore act not just as universal sorbents for soaking up a wide range of chemicals, but also as a new way to decontaminate stockpiles of chemical weapons.
