Schematic of (a) maleic acid tertiary amide bonds constructed from maleic anhydrides and secondary amines; and (b) polymer networks prepared from bifunctional maleic anhydrides and multifunctional secondary amines and their depolymerization in acid aqueous solution. Two monomers can be separated and regained in a closed-looped recycling process.
