Abstract
This article summarizes our recent efforts to chemical recycling of polymeric materials based on the equilibrium polymerization character of cyclic monomers. Spiro orthoesters (SOEs), bicyclo orthoester, cyclic carbonates, and dithiocarbonates undergo ring-opening polymerization to afford the corresponding polymers, and the resulting polymers depolymerize to give the starting monomers under cationic or anionic conditions. Further, crosslinking and decrosslinking systems of bifunctional SOEs and a polymer having SOE moiety in the side chain are described.
