Abstract
The alternating copolymerization of epoxides with carbon dioxide to give aliphatic polycarbonates, pioneered by Inoue and coworkers in the 1960s,1 has attracted much attention as one of the most promising processes for CO2 utilization.2 In the last decade, a variety of catalyst systems based on metal–salen complexes have been developed,2c,3–5 many of which show much higher catalytic activities than other conventional systems. Unfortunately, however, because metal–salen complexes are highly coloured, even a small amount of residual metal–salen complexes in the product polycarbonates leads to undesired coloration of these inherently colourless copolymers. In addition, highly active catalyst systems usually employ cobalt4,6 or chromium5,7 complexes, and contamination of these metals in the product polycarbonates could also be problematic due to their toxicity. It is therefore highly desirable to develop a method that allows for easy and efficient removal of these metal complexes from the polymers in this alternating copolymerization.
