Scientists turned carbon dioxide into high-performance polyester; the material can be chemically recycled into reusable building blocks |
Carbon dioxide is abundant but chemically inert, which makes it difficult to turn into useful polymers. A study describes a closed-loop platform that uses carbon dioxide with bicycloalkanes to make high-performance, recyclable polyesters. They used bicyclic butane, or BCB, and bicyclic pentane, or BCP, monomers in a direct alternating copolymerization. A simple organic catalyst initiated…
