Abstract

A catalyst-free amino-alcoholysis depolymerization protocol was explored for the chemical recycling of poly(bisphenol A carbonate) (BPA-PC). Under mild conditions, the initial monomer bisphenol A (BPA) and value-added oxazolidinone chemicals were recovered with high efficiency and yield. The chemical cycle was closed by producing new BPA-PC from recovered BPA.
