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 cyclic carbonate contents in the product are 5.0%-11.3% at 25-60 ℃, better than those from homogeneous catalysis. Moreover, the copolymer with 70.7% carbonate content presents high thermal decomposition temperature of 250 ℃ and relatively high glass-transition temperature (Tg) of 31.2 ℃.
