Chemical Recycling of Poly(Cyclohexene Carbonate) Using a Di-Mg Catalyst.

Chemical recycling of polymers to true monomers is pivotal for a circular plastics economy. Here, the first catalyzed chemical recycling of the widely investigated carbon dioxide derived polymer, poly(cyclohexene carbonate), to cyclohexene oxide and carbon dioxide is reported. The reaction requires dinuclear catalysis, with the di-Mg catalyst showing both high monomer selectivity (>98 %) and activity (TOF=150 h , 0.
