Abstract

It is of great interest to make a degradable material widely tailorable to replace petroleum-derived products among diverse applications. Here, we report the construction of a new multi-purpose degradable material for the first time via a simple ternary copolymerization system comprising ε-caprolactone (ε-CL), cyclohexane oxide (CHO) and CO2. Under low pressure of 1 bar ∼5 bar, the ring-opening polymerization (ROP) of ε-CL and ring-opening copolymerization (ROCOP) of CO2 and CHO can simultaneously proceed. The carbonate units are randomly distributed on the polymer chain. These random terpolymers have controllable molar mass (10–106 kDa) and compositions (4–33 mol% CO2). And the obtained materials show large-span tunability from tough plastic to elastomer and even adhesive.
