A low temperature and solvent-free method to depolymerize polymers made by ATRP and RAFT is reported. By performing an efficient end-group modification, the modified polymers were subsequently successfully depolymerized, resulting in up to 90 % monomer regeneration at temperatures as low as 220 °C. Importantly, the process was scalable and the monomer produced had high purity and could subsequently be used to make a new batch of polymer.
