Preparation of polyethylene vitrimer by using reactive processing

As covalent adaptable networks (CANs) have emerged as a promising approach for designingadvanced polymeric materials, their application in modifying polyethylene (PE) is particularlyintriguing. However, the inherent limitations of PE, such as its low reactivity and lack of dynamiccovalent bonds, pose a challenge for the development of PE-based CANs. This study explores thepotential of incorporating dynamic covalent chemistries into PE to create adaptable networks. Here,we propose strategies for introducing functional groups or moieties that can undergo reversiblecovalent reactions, enabling the manipulation of the PE network's structure and properties on demand.The successful implementation of CAN principles in PE could unlock exciting possibilities for selfhealingmaterials, recyclable plastics, and adaptable composites
