Recycling polymers to their monomers would enable a circular polymer economy, but this can be challenging, especially for materials with all-carbon backbones. Now, by lowering the strain of cyclooctene through ring fusion, recyclable polymers with useful physical properties can be made by an olefin-metathesis-based route.
