A major environmental challenge has resulted from the use and disposal of plastics without any consideration for end-of-life recycling or degradation. Plastic pollution stems from the fact that many commercial polymers feature an inert hydrocarbon backbone which take thousands of years to degrade. The incorporation of degradable units into conventional polymers has emerged as a promising strategy to produce degradable versions of commercially relevant polymers, potentially enabling recycling and biodegradation on a significantly shorter time-scale. Dithiane, a six-membered cyclic disulfide, has appropriate reactivity to copolymerize with less activated monomers such as vinyl acetate. In this work, poly(dithiane-co-vinyl acetate) was synthesized and characterized by NMR and GPC. Thermal degradation of this polymer was investigated and optimized by tuning dithiane content, temperature, and concentrations.
