This paper describes the first example of alternating copolymerization of carbonyl sulfide (COS) with cyclohexene oxide (CHO) via heterogenous catalysis of a nano-lamellar zinc–cobalt(III) double metal cyanide complex (Zn–Co(III) DMCC), providing an efficient method for converting COS to poly(cyclohexene monothiocarbonate) (PCHMTC) with an alternating degree up to 93%. The number-average molecular...
Epichlorohydrin (ECH), as a cheap raw chemical material, is an ideal monomer for copolymerization with CO2 to produce biodegradable polycarbonates. This work describes the selective ECH–CO2 copolymerization via heterogeneous catalysis of nanolamellar zinc–cobalt double metal cyanide complex (Zn–Co (III) DMCC), affording a poly(carbonate–co–ether) with carbonate content up to 70.7%. Remarkably, the...
Traditional cobalt-zinc double metal cyanide complex [Zn–Co(III)DMCC] catalysts could catalyze the copolymerization of carbon dioxide (CO 2 ) with propylene oxide (PO) to afford poly (propylene carbonate) (PPC) with high productivity. But the molecular weight (MW) of PPC and the polycarbonate selectivity were not satisfied. In this work, by using a nanolamellar Zn–Co(III) DMCC catalyst, the...
