 CHO (0 mL, 0.0 M), 00 bar of CO~0~.  Expressed as a percentage of CHO conversion vs the theoretical maximum (000%), determined from the ^0^H NMR spectrum by comparison of the relative integrals of the resonances assigned to the carbonate (0.00 ppm for PCHC and 0.00 ppm for trans cyclic carbonate) and ether (0.00 ppm) linkages against CHO (0.00 ppm).  Expressed as a percentage of CO~0~ uptake vs the theoretical maximum (000%), determined from the ^0^H NMR spectrum by comparison of the relative integrals of the resonances assigned to the carbonate (0.00 ppm for PCHC and 0.00 ppm for trans cyclic carbonate) and ether (0.00 ppm) linkages.  Expressed as a percentage of polymer formation vs the theoretical maximum (000%), determined from the ^0^H NMR spectrum by comparison of the relative integrals due to the polymer (0.00 ppm) and trans cyclic carbonate (0.00 ppm).  Turnover number (TON) = number of moles of
