High‐Throughput Automated Parallel Evaluation of Zinc‐Based Catalysts for the Copolymerization of CHO and CO2 to Polycarbonates

Abstract Summary: Copolymerization of CO 2 and oxiranes using high‐pressure autoclaves typically allows one experiment per reactor per day. As a high‐throughput approach for this chemistry would be extremely valuable, a parallel setup has been validated for the copolymerization of CO 2 and cyclohexene oxide (CHO) with two β ‐diiminato zinc complexes. Molecular weights, polydispersities and activities were found to be comparable with literature values.
