The condensation of a mixture of dimethyl carbonate and phthalate derivatives with 1,4‐butanediol (BD), catalyzed by sodium alkoxide, generated high‐molecular weight poly(1,4‐butylene carbonate‐co‐aromatic ester)s with molecular weights (Mn) of 50–120 kDa. The subsequent addition of polyols [BD, glycerol propoxylate, 1,1,1‐tris(hydroxymethyl)ethane, or pentaerythritol] chopped these high‐molecular weight polymers to afford macrodiols or macropolyols with facile control of their molecular weights (Mn, 2000–3000 Da) and unique chain topological compositions. Macropolyols prepared by chopping poly(1,4‐butylene carbonate‐co‐terephthalate) were waxy in nature, whereas those containing isophthalate and phthalate units were oily. The macropolyols synthesized by this chopping method may have potential applications in the polyurethane industry. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43754.

Click chemistry, one of the most important methods in conjugation, plays an extremely significant role in the synthesis of functional aliphatic polycarbonates, which are a group of biodegradable polymers containing carbonate bonds in their main chains. To date, more than 75 articles have been reported on the topic of click chemistry in functional aliphatic polycarbonates. However, these efforts have not yet been highlighted. Six categories of click reactions (alkyne-azide reaction, thiol-ene reaction, Michael addition, epoxy-amine/thiol reaction, Diels-Alder reaction, and imine formation) that have been afforded for further post-polymerization modification of polycarbonates are reviewed. Through this review, a comprehensive understanding of functional aliphatic polycarbonates aims to afford insight on the design of polycarbonates for further post-polymerization modification via click chemistry and the expectation of the practical application.

“…In contrast, a large variety of epoxides for direct copolymerization of epoxides and CO 2 is conveniently available. Also their synthesis is often based on one or two steps, which holds especially for glycidyl ethers …”

Aliphatic polycarbonates synthesized from carbon dioxide (CO 2 ) and epoxides are resource-saving, highly biocompatible and biodegradable polymers. Since the discovery of the copolymerization of epoxides and CO 2 in 1969 by Inoue et al., this has become an important and useful technology for the large-scale utilization of CO 2 in chemical synthesis, employing mainly propylene oxide, and cyclohexene oxide (CHO). Only in recent years, functionalized polycarbonates have become an emerging topic with a broad scope of potential applications. This review summarizes synthetic routes and properties of numerous functionalized polycarbonates synthesized from CO 2 and functional epoxide monomers. Implications for new materials and possible applications, for instance for pharmaceutical purposes and membranes are reviewed. Besides polycarbonates based on oxirane and CHO derivatives, particular emphasis is placed on the manifold synthetic approaches and postpolymerization modifications of glycidyl ether based polycarbonates. Not only functionalized linear polycarbonates are presented but also a variety of novel polycarbonate architectures, e.g., star and hyperbranched polymers.
