Direct Monomer Recovery from Ring-Closing Depolymerization of Thermosets.

ABSTRACT: Recovering monomers from the depolymerization of thermosets presents a significant challenge, which becomes even more daunting if one sets the goal of doing it directly, i.e., without complex chemical separation steps. To this end, we have synthesized a new type of polycarbonate thermoset by first copolymerizing alkyl cyclic carbonates (ACCs) with small amounts of allyloxy cyclic carbonates (AoCCs), followed by cross-linking the resulting allyloxy polycarbonate with excess tetrathiol compounds under UV irradiation. These cross-linked polycarbonates demonstrate enhanced thermal and mechanical properties compared to their linear analogues, while maintaining the linear polymers' capacity for ring-closing depolymerization. The depolymerization process enables the direct recovery
