Propargyl‐Functional Aliphatic Polycarbonate Obtained from Carbon Dioxide and Glycidyl Propargyl Ether

The synthesis of propargyl‐functional poly(carbonate)s with different content of glycidyl propargyl ether (GPE) units is achieved via the copolymerization of propargyl glycidyl ether and carbon dioxide. A new type of functional poly(carbonate) synthesized directly from CO 2 and the glycidyl ether is obtained. The resulting polymers show moderate polydispersities in the range of 1.6–2.5 and molecular weights in the range of 7000–10 500 g mol −1 . The synthesized copolymers with varying number of alkyne functionalities and benzyl azide are used for the copper‐catalyzed Huisgen‐1,3‐dipolar addition. Moreover, the presence of vicinal alkyne groups opens a general pathway to produce functional aliphatic poly(carbonate)s from a single polymer scaffold.
