Although plastics (polymers) have become necessary for a variety of technologies and functions, their large consumption has led to negative impacts on the environment as well as resulted in a plastic pollution crisis. This urges a need to seek more environmentally friendly alternatives (aliphatic polyesters) to mass-produced plastics in order to combat this issue. An attractive route toward these polyesters is through the ring-opening copolymerization (ROCOP) of cyclic ethers (epoxides or THF) and cyclic anhydrides. This route allows access to a wide scope of monomers, thus potentially leading to a library of plastics with varying properties. Herein, Lewis acid catalysts that are metal-free or contain rare earth metal centers were employed for the targeted ROCOP. To further address the plastics issue, there is also a need to develop better methods to chemically recycled/upcycle currently mass-produced plastics. As polyethylene (PE) is one of the most widely consumed plastics, efforts described herein were directed towards using a Lewis acid catalyst (AlCl3 or rare earth metal salts) for the degradation of PE into the value-added products, diaryl alkanes.
