The production of commodity plastic is predicted to increase substantially in upcoming decades.1 Many common plastics are derived from petroleum, which is a finite resource. Because of this, much work has been done to design materials based on sustainable feedstocks.2 Carbon dioxide, which is abundantly available, is an appealing source of carbon and is already used in numerous chemical processes.3 In this presentation, the reaction of carbon dioxide with epoxides to form cyclic carbonates will be discussed with an emphasis on application to sustainable non-isocynate polyurethanes (NIPUs).4 NIPUs offer advantages over traditional polyurethanes and have a wide variety of applications including films, self-healing materials, and nanocomposites.5,6,7 Advances in NIPUs are leading toward sustainable alternatives to traditional polyurethanes.
