Their behavior was compared with that of traditional salen chromium complexes. A completely alternating enchainment of monomers to provide pure polyesters was achieved with all the catalysts when used in combination with 4-(dimethylamino)pyridine (DMAP) as the cocatalyst. Poly(propylene maleate-block-polyglycolide), a diblock polyester with a precise composition, was obtained by switch catalysis, in which the same catalyst was able to combine the ROCOP of propylene oxide and maleic anhydride with the ring-opening polymerization (ROP) of glycolide (GA) through a one-pot procedure, starting from an initial mixture of the three different monomers.<\/jats:p>","DOI":"10.3390\/ijms241210052","type":"journal-article","created":{"date-parts":[[2023,6,13]],"date-time":"2023-06-13T01:35:30Z","timestamp":1686620130000},"page":"10052","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Salen-like Chromium and Aluminum Complexes as Catalysts in the Copolymerization of Epoxides with Cyclic Anhydrides for the Synthesis of Polyesters"],"prefix":"10.3390","volume":"24","author":[{"given":"Federica","family":"Santulli","sequence":"first","affiliation":[{"name":"Department of Chemistry and Biology \u201cA.
