However, plastics that can be so easily depolymerized lack suitable mechanical and thermal properties to be widely useful. This is the central paradox of the plastic problem: Although we desire our plastics to be readily recyclable or not to persist in the environment, they must also be sufficiently robust to function in their desired application.
