摘要
Cross-linked polymer networks with highly cross-linking chemical structures constructed via dynamic covalent bonds can provide polymers with excellent physical and mechanical properties, and also good self-healing ability and reprocessability through chain rearrangement. The technique shows great potential application in industry by breaking the boundaries between thermoplastic and thermoset polymers. In this review, based on dynamic covalent mechanisms of transesterification, disulfide exchange, siloxane silanol exchange, olefin cross-metathesis, imine exchange and acylhydrazone exchange reactions, preparation and properties of reprocessable cross-linked polymers with these dynamic covalent bonds are introduced in detail. Furthermore, existing problems and development prospects in dynamic covalent cross-linked polymers are discussed. © 2020, Editorial Board of Journal of Chemical Engineering of Chinese Universities".
