Organocatalytic depolymerization of poly(limonene carbonate) and related macromolecules is reported. The main degradation product, limonene carbonate, can be repolymerized via ring-opening polymerization using the same organocatalyst providing a potential circular process. The mechanistic intricacies of this polymer depolymerization have been scrutinized in detail revealing the concomitant occurrence of complementary and unique degradation modes.
