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.
