The utilization of carbon dioxide in polymer synthesis is an attractive strategy for sustainable materials. Electrochemical CO2 reduction would offer a natural starting point for producing monomers, but the conditions of electrocatalysis are often drastically different from the conditions of organometallic coordination-insertion polymerization. Reported here is a strategy for integrating electrochemical and organometallic catalysts that enables polyketone synthesis from CO2 and ethylene in a single multicompartment reactor. Polyketone materials that are up to 50% derived from CO2 can be prepared in this way. Potentiostatic control over the CO-producing catalyst enables the controlled generation of low-pressure CO, which in conjunction with a palladium phosphine sulfonate organometallic catalyst enables copolymerization to nonalternating polyketones with the CO content tuned based on the applied current density
