Recent Advances

Poly(α-hydroxy acids), as a family of biodegradable polyesters, are valuable materials due to their broad applications in packaging, agriculture, and biomedical engineering. Herein we highlight and explore recent advances of catalysts in controlled ring-opening polymerization of O-carboxyanhydrides towards functionalized poly(α-hydroxy acids), especially metal catalyst-mediated controlled polymerization. Limitations of current polymerization strategies of O-carboxyanhydrides are discussed.

The Future

Hyperbranched polymers (HBPs) have been applied in various fields because of its outstanding biodegradability and biocompatibility. At present, there are a variety of methods that are used to fabricate HBPs, such as polycondensation, reactive polymerization and ring-opening polymerization according to reaction mechanism. These methods are all environmental-friendly and high-efficient to generate HBPs, and are valuable for industrialization. In this work, we conclude some common methods of HBPs fabrication and make the comparison between them to analyze their advantages and disadvantages, which contribute in how to improve the synthesis process in the future research.
