This paper reviewed the research progress in the applications of dynamic covalent cross-linking networks in sev-eral major thermoplastic polymers,including polyolefins,polystyrene,poly(methyl methacrylate),and polyesters.Through introducing dynamic covalent bonds,the resultant materials obtained an enhancement in melt strength,mechani-cal properties,heat resistance,and solvent resistance along with well maintainability of their inherent characteristics.However,there still have some challenges such as complex fabrication processes,high costs,and insufficient research on long-term stability and degradation in spite of significant advancements.Future research was suggested to focus on opti-mizing the preparation methods,enhancing the material properties,and investigating the long-term stability under vari-ous environmental conditions to promote the large-scale industrial applications of the dynamic covalent cross-linking tech-nology.
