Chemical Recycling of Polyesters to Cyclic Anhydrides and Valuable Chemicals Enabled by Zinc Catalysts
Chemical recycling of polyesters to re-form the constituent monomers is essential for a circular plastic economy. The ring-opening copolymerization (ROCOP) of epoxides and cyclic anhydrides represents an important route to polyesters and has received considerable attention over the past decades. In contrast, the chem...
