摘　　要：综述了动态共价交联网络在几种主要的热塑性塑料中的应用研究进展,包括聚烯烃、聚苯乙烯、聚甲基丙烯酸甲酯和聚酯。通过引入动态共价键,这些材料在保持原有特性的基础上,实现了熔体强度、力学性能、耐热性和耐溶剂等性能的提升。然而,尽管目前取得了诸多进展,动态共价交联技术在实际应用中仍面临一些挑战,如制备工艺复杂、成本较高以及长期稳定性和降解行为的研究不足。未来的研究应重点关注优化制备工艺、提升材料性能以及研究材料在各种环境条件下的长期稳定性,以推动动态共价交联技术在工业中的大规模应用。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.
