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

Abstract

As a classic CO2-based material, it is important to enable the full utilization of high performance poly(cyclohexene carbonate) (PCHC), which is derived from the copolymerization of CO2 and cyclohexene oxide (CHO). However, examples of sophisticated and advanced functionalization of PCHC are still scarce. Herein, we report a facile and feasible strategy to transform brittle plastic PCHC into an elastomer by the introduction of Cu–S dynamic reversible bonds via CO2/CHO/vinyl cyclohexene oxide terpolymerization followed by thiol–ene click chemistry and Cu–S coordination postfunctionalization. The resulting thermoplastic elastomers displayed good elastic recovery (remaining at 86% strength after five cyclic tests), a certain hardness (Shore A from 31 to 91), and adjustable mechanical properties. The present study provides a platform for the further utilization of high value-added CO2-based materials.
