摘要

后聚合改性已应用于废旧塑料的升级转化，它可在保持聚合物骨架完整的情况下，赋予塑料新的功能和特性，为废旧塑料的回收利用提供另一条可行途径。本文综述了近年来采用后聚合改性升级法将废旧塑料转化为增值材料的相关进展，重点介绍了后聚合改性方法在聚苯乙烯(PS)、聚氯乙烯(PVC)、聚乙烯(PE)、聚丙烯(PP)、聚对苯二甲酸乙二醇酯(PET)功能化改性方面应用的研究成果，并对该领域未来的研究提出思考和展望，为后续更加深入的研究提供相关的依据和参考。

Abstract

Post-polymerization modification has been applied to upgrade and transform waste plastics. This can endow plastics with new functions and properties while maintaining the integrity of the polymer backbone

providing another feasible method for recycling waste plastics. Recent progress in the conversion of waste plastics into value-added materials using post-polymerization modification and upgrading methods has been reviewed. This review focuses on the research achievements regarding the application of post-polymerization modification methods for the functional modification of polystyrene (PS)

poly(vinyl chloride) (PVC)

polyethylene (PE)

polypropylene (PP)

and poly(ethylene terephthalate) (PET). Moreover

it presents thoughts and prospects for future research in this field

providing a relevant basis and reference for more in-depth follow-up research.
