The alternating copolymerization of (R)- or (S)-limonene oxide and CO2using β-diiminate zinc acetate catalysts is reported. At 100 psi CO2and 25 °C, the catalyst exhibits a high selectivity for the trans isomer and produces regioregular polycarbonate. The copolymer contains >99% carbonate linkages, a narrow molecular weight distribution, and anMnvalue consistent with the [epoxide]/[Zn] ratio.
