(57g) Controlled Depolymerization and Upcycling of PVC

PVC is the 3rd most produced plastic worldwide. Rigid PVC is the common material of construction for most modern plumbing systems, and other forms of PVC find their way into a wide range of consumer products. The presence of chlorine atoms in PVC presents unique challenges for its disposal as the uncontrolled decomposition of PVC releases HCl and chlorinated organic compounds, presenting waste management and environmental problems. However, the design of chemical reactions and processes which control the decomposition of PVC affords unique opportunities for depolymerization and upcycling. This presentation will detail our efforts to date in the conversion of waste PVC into an array of value-added small molecules and polymer products.
