Among the plastics produced around the world, polyolefins are the most used in human daily life and make up about two-thirds of the plastics produced in the world. Also, the most plastic waste is related to polyolefins, which are non-biodegradable plastics. One of the things that have challenged the recycling of polyolefins by traditional methods such as mechanical recycling is the loss of mechanical and rheological properties as well as their degradation. One of the methods of improving properties and postponing degradation is the use of vitrimerization reactions, as a result of which, in thermoplastics, a compatible covalent network is created, which gives the plastic the ability to behave...
