Converting CO 2 into polymer : A catalytic system that produces a high molecular weight CO 2 /propylene oxide copolymer with high activity and selectivity is disclosed. After filtration through silica gel, elution of the catalyst leaves a solid phase with a negligible metal residue (see picture). The catalyst can be reused without significant loss of performance.
