One-pot synthesis and postpolymerization functionalization of cyclic carbonate/epoxide-difunctional polycarbonates prepared by regioselective diepoxide/CO2 copolymerization†
Abstract
Novel aliphatic polycarbonates with a tunable number of cyclic carbonate and epoxide dual functional groups were synthesized via an (ONSO)CrCl-mediated copolymerization of 4-vinyl-1-cyclohexene diepoxide with carbon dioxide in one pot. The resulting difunctional polycarbonates with high Tg afforded a versatile platform for the postpolymerization functionalization.
