Facile synthesis of a sponge
(Do not rub on skin.)
Schwarz and Epple report that the simple heating of sodium chloroacetate results in "highly porous" polyglycolide after water washing to remove NaCl
byproduct, with a pore fraction of about 50% and pore sizes in the micrometer range. This was achieved by gradual heating to 160-180 C, with caution
to avoid an exothermic decomposition that ruins the product.
It is not immediately obvious what the potential applications are, but the ability to simply make a sponge-like product out of a relatively simple
precursor is, at least, rather interesting. I would not recommend using this on any living being since we cannot be sure if there are no contaminants
in the product, but it may have other uses.

Can't be worse than lead sponge! 
It definitely is. I love the photo they provided. Spongy!
