Activation and copolymerization of CO2 by macromolecule‐metal complexes

The activation of CO2 and relevant comonomers can be promoted by using catalysts consisting of appropriate chelating polymers, suitable bimetallic combinations, and prepared by appropriate procedures. In this way, aliphatic polycarbonates, polycarbonate‐polyurethanes, saturated and unsaturated polycarbonate‐polyesters, as well as some other copolymers were synthesized in high yields.
