From plastic to elastomers: introducing reversible copper–thioether coordination in CO₂-based polycarbonate

Abstract

As a classic CO2-based material, it is meaningful and striking to full utilization of the high performance poly (cyclohexene carbonate) (PCHC), which is derived from the copolymerization of CO2 and...

Post-polymerization functionalization of aliphatic polycarbonates using click chemistry

“…The subsequent introduction of copper enables dynamic, reversible coordination with sulfur, thereby converting the rigid polymer into an elastomeric material. 92 In addition to all of these post-polymerization modifications, thiol-ene click chemistry has been utilized for crosslinking various cyclic carbonate-based polycarbonates providing diverse applications such as nanosponges, hydrogels, 3D printed porous materials and elastic polymers.

Cd(ii) and Zn(ii) coordination polymer-assisted CO2/cyclohexene oxide copolymerization with a double metal cyanide catalyst

“…Recently, the same group studied the copolymerization of CO 2 with cyclohexene oxide (CHO) heterogeneously catalyzed by double metal cyanide (DMC) at 80 °C and 3 MPa CO 2 . 7 As a result, the F (CO 2 ) value is 96% and the conversion rate of CHO is 99%. In the last decades, DMC was found to be efficient for binary and ternary copolymerization with advantages of simple preparation, low synthetic cost and insensitivity to water and air.…”
