GPC chromatograms of MCO ED-ROP experiments conducted within a DSC pan with a 2 mol% CsF initiator, demonstrating that heating to 320 °C (B) could form a higher-molecular-weight polymer shoulder. Heating to >400 °C (C) or <300 °C (A) yielded chromatograms with molecular weights similar to the starting MCOs, though in the samples heated at higher temperatures, there was a lower detector response and much more insoluble material had been filtered off.
