Provided herein is technology relating to depolymerization of polymers and particularly, but not exclusively, to methods and systems for de-crosslinking polyacrylate salt-based polymers and other polymers and compositions made from de-crosslinking polyacrylate salt-based polymers and other polymers.

Depolymerization of polymers

Methods for upcycling crosslinked sodium polyacrylate to pressure sensitive adhesives via (a) mechanochemical chain-shortening and esterification or (b) esterifying with high conversion with a Fischer esterification process are disclosed. Also disclosed is a pressure sensitive adhesive prepared by the disclosed methods and articles comprising the pressure sensitive adhesive, including, but not limited to, pressure sensitive tape, a bandage, a label, note pads, a decal, a stamp, an envelope, a sticker, packaging, automobile trim, and a film.

Super absorbent polymer recycling to pressure sensitive adhesives

Provided herein are nickel(O) catalysts that are stable when exposed to air and can be used to catalyze the formation of a C&#x2014;C, C&#x2014;O, or C&#x2014;N bond.
