All the 1-alkyl-3-methyl imidazolium chlorides showed very high carbonate content. The turnover number (TON) and average molecular weight of the copolymer were affected by the structure of the imidazolium salt ionic liquid; the one with the cation of longer alkyl chain length and with more nucleophilic anion showed better reactivity. However, TON decreased when hexyl or octyl containing ionic liquids were used probably due to their steric hindrance. The effects of reaction temperature, carbon dioxide pressure, and reaction time on the carbonate content and TON of the polycarbonates are also discussed. Tetrabutylammonium chloride (TBAC) was also tested for this reaction to compare its catalytic performance with the ionic liquids.
