Alternating CO 2 and bicycloalkane copolymerization to circular polyesters

TL;DR - A simple organic catalyst directly copolymerizes CO₂ with bicycloalkanes into high-performance polyesters. Selective depolymerization enables closed-loop recycling, potentially reducing both fossil feedstock use and plastic waste.

• Produces alternating polyesters directly from CO₂ and bicycloalkanes.
• Uses a simple organic catalyst.
• Supports selective depolymerization and material recovery.
• Combines high-performance properties with a circular lifecycle.
