What's Happening?
A recent study has successfully developed a controlled ring-opening alternating copolymerization (ROAC) method using organobase catalysts to synthesize crystalline polyesters. This method addresses the challenges typically associated with ROAC, such as low reactivity and side reactions, by utilizing isobutylene oxide (IBO), a highly symmetric epoxide. The study demonstrates that using t-BuP2 as a catalyst allows the ROAC of phthalic anhydride (PA) and IBO to proceed smoothly, resulting in crystalline polyesters with narrow molecular weight distribution. This approach has been extended to other cyclic anhydrides and initiators, enabling the synthesis of polyesters with diverse structures. The research expands the scope of epoxides in ROAC and provides a precise strategy for macromolecular designs.
