Li, Chunliang Sablong, Rafaël J. A. T. M. van Benthem, Rolf Koning, Cor E. Unique Base-Initiated Depolymerization of Limonene-Derived Polycarbonates The depolymerization of poly­(limonene carbonate) (PLC) initiated by 1,5,7-triazabicyclo[4.4.0]­dec-5-ene (TBD) was investigated. The strong organic base TBD was capable of deprotonating the OH-terminated PLC, leading to fast degradation via backbiting reactions at high temperature. An interesting feature of the base-initiated breakdown of PLC lies in the quantitative depolymerization into the corresponding initial limonene oxide monomer. This result implies the complete back-to-monomer recyclability of the fully biobased PLC, which accordingly can be considered as a really sustainable material. Additionally, the stability of PLC when exposed to TBD was enhanced by an end-capping reaction, which further supported the proposed degradation pathway. base TBD;Unique Base-Initiated Depolymerization;backbiting reactions;depolymerization;OH-terminated PLC;base-initiated breakdown;Limonene-Derived Polycarbonates;back-to-monomer recyclability;end-capping reaction;biobased PLC;degradation pathway;limonene oxide monomer 2017-06-15
