Description

Application

• Enhanced poly(propylene carbonate) synthesis: Enhanced poly(propylene carbonate) materials were developed through a one-pot synthesis from carbon dioxide, propylene oxide, and a carboxylic dianhydride, showing significant improvements in yield strength when the feed molar ratio of dianhydride to propylene oxide was increased (X Chen et al., 2018).


• Copolymerization with carbon dioxide: A study on the copolymerization and terpolymerization of carbon dioxide/propylene oxide/phthalic anhydride using a cobalt salen complex demonstrated efficient synthesis without forming ether linkages (JY Jeon et al., 2014).


• Polymer architectures: Innovative polymer architectures were explored in the synthesis of poly(ethylene oxide), propylene oxide, and other alkylene oxides, which include novel bioconjugation techniques (J Herzberger et al., 2016).
