The synthesis of aliphatic polycarbonates derived from epoxides and carbon dioxide offers a promising alternative to fossil fuel-based bisphenol-A polycarbonates. The ring-opening copolymerization (ROCOP) of cyclohexene oxide and CO
2 yields the rather brittle poly(cyclohexene carbonate) (PCHC). Within this work, the mechanism of the ROCOP was successfully coupled with other distinct polymerization mechanisms, e.g. the ring-opening polymerization of ß-butyrolactone. A chemoselective CO
2-switch allowed the tailoring of the polymer’s architecture and a reduced brittleness of PCHC.
