The copolymerization of cyclohexene oxide (CHO) and carbon dioxide (CO2) was carried out under supercritical CO2 (scCO2) conditions to afford poly (cyclohexene carbonate)(PCHC) in high yield. The scCO2 provided not only the C1 feedstock but also proved to be a very efficient solvent and processing aid for this copolymerization system. Double metal cyanide (DMC) and salen Co(III) catalysts were employed, demonstrating excellent CO2/CHO copolymerization with high yield and high selectivity.

All sessions were video recorded and analysed for percentage engagement and percentage errors made by each of four students. For each student individually, these outcome measures were then compared between the two conditions. The teachers were interviewed at the end of the study.
