Two examples are presented for the synthesis of optically active polymers with main-chain chirality from achiral monomers using chiral metal-complexes as catalysts. Asymmetric alternating copolymerization of α-olefins with carbon monoxide provided optically active polyketones when catalyzed by an (R,S)-BINAPHOS–Pd complex. From propene and CO, highly isotactic polyketone with high enantioselect...

Abstract The degradation of plastics has attracted much attention from the global community. Polyethylenes (PEs) as most abundant synthetic are mostly studied. PE is non-degradable and non-polar because sole presence pure hydrocarbon components. Concurrent incorporation both in-chain cleavable functional groups into chain an effective pathway to overcome issue; however, method for achieving thi...
