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.

Radical Ring-Opening polymerization (rROP) of Cyclic Ketene Acetals (CKAs) combines the advantages of both ring-opening and radical polymerization thereby allowing the robust production of polyesters. In this article we investigate in detail the radical ring-opening polymerization of model CKA monomers and demonstrate by the combination of DFT calculations and kinetic modeling using PREDICI software that we are now able to predict <i>in silico</i> the ring-opening ability of CKA monomers<br>
