Despite significant advancements in thermal and photothermal depolymerizations, the success of these techniques relies on tedious deoxygenation procedures. Herein, we report development depolymerization technique efficient without prior deoxygenation, which was enabled by copper/ligand complexes inclusion (0.25 wt% relative to solvent) zinc oxide (ZnO) nanocrystals activated UV light. This approach tested for poly(methyl methacrylate) (PMMA) prepared atom transfer radical polymerization (ATRP); effects solvent polarity activity ligands were investigated. Unexpectedly, a low-activity Cu-complex with 2,2'-bipyridyne ligand, combination low-polarity solvent, 1,2,4-trichlorobenzene, relatively high yields less than 1 h at 150 °C. Higher ATRP tris(2-pyridylmethyl)amine (TPMA) N,N,N',N'',N''-pentamethyldiethylenetriamine (PMDETA) ligands, efficient, associated their decomposition and/or excessive formation radicals premature termination chain ends. The presented facile designed be used even partially aerated reactors, opening new avenues depolymerization.
