Stereoselective ring-opening polymerization of functional β-lactones: influence of the exocyclic side-group
Polyhydroxyalkanoates (PHAs) are a unique class of polyesters especially due to their chemical diversity imparted by their side-chain substituent that provides a handle to tune their properties, such as their thermal, mechanical and (bio)degradability signature.
