The synthesis of 100% 13C-labelled poly(propylene carbonate) from the completely alternating copolymerization of propylene oxide (rac-PO and R(+)PO) and 13CO2 is reported. The prepared copolymers were shown to be regioselective with predominately head-to-tail (HT) connectivity. The infrared absorption of the polycarbonate in the \(v_{{\mathrm{co}}_{\mathrm{3}}}\) region is red-shifted by 45 cm−1 from the polymer prepared from 12CO2. This shift in frequency allows for the observation of vNO modes of incorporated dinitrosyl metal complexes.
