Abstract
Methods of polymer and/or oligomer depolymerization are described herein which, in some embodiments, enable facile polymer and/or oligomer decomposition under mild, non-energy intensive conditions. Briefly, a method of depolymerization comprises providing a reaction mixture comprising a transition metal catalyst, and a polymer or oligomer having a backbone including cyclobutane units, and decomposing the polymer or oligomer to provide diene monomer or alkene monomer.
