Direct Monomer Recovery from Ring-Closing Depolymerization of Thermosets

Francesco Stellacci, Youwei Ma

Recovering monomers from the depolymerization of thermosets presents a significant challenge, which becomes even more daunting if one sets the goal of doing it directly, i.e., without complex chemical separation steps. To this end, we have synthesized a ne ...
