High-Tg Polythioesters From Isomerization Ring-Opening Polymerization of a Renewable Oxanorbornane-Fused Thionolactone.
Polythioesters are gaining increasing interest due to their attractive material properties and improved end-of-life options. However, the lower ring strain of thiolactones compared to lactones limits the accessibility of polythioesters through conventional ring-opening polymerization. Thionolactone isomerization ring-o...
