Alternating CO 2 and bicycloalkane copolymerization to circular polyesters.

Transforming abundant but inert CO 2 into useful polymers has been pursued since the 1960s (ref.

Transforming abundant but inert CO 2 into useful polymers has been pursued since the 1960s (ref. 1 ) and has typically been achieved by copolymerization with a reactive comonomer, aided by a catalyst, which can address both thermodynamic constraints and high kinetic barriers…
