Abstract
Using chemical methods to depolymerize or convert plastic materials for recycling is a useful process to achieve the sustainable and circular plastic economy. Herein, different from conventional chemical methodologies to convert waste plastics into monomers or high value-added chemicals, a “waste polymer to precursor of polymer to new polymer” protocol was proposed. For the chemical recycling of poly(bisphenol A carbonate) (BPA-PC), a novel carbonate exchange strategy was explored, in which BPA-PC was depolymerized into the “DPC-PC” via diphenyl carbonate (DPC) mediated carbonate exchange reaction. The unique structure enables DPC-PC to serve as a curing agent for preparing high-performance and recyclable epoxy thermoset, thus blazing a new trail for the chemical recycling of BPA-PC.
