Traditional aliphatic polyesters are hydrophobic, lacking polar or functional groups, which limits their application in the delivery of biomacromolecules like proteins, peptides, and nucleic acids. This review presents a summary of the research progress on the controlled ring-opening polymerization of functional lactones and O -carboxyanhydrides (OCAs), leading to various novel polyesters with in-chain or side-chain functional groups. These polyesters with defined molar masses and location of functionalities may facilitate biomaterials’ applications.
