Polyolefins (POs), which constitute over 50% of all plastics, predominantly end up in landfills. To date, there have been no reports on mixtures PO vitrimers. This study the successful synthesis vitrimers from a mixture 27.7% high-density polyethylene (HDPE), 36.3% linear low-density (LLDPE)/low-density (LDPE), and 36.0% polypropylene (PP), is similar to that Municipal Solid Waste (MSW). achieved by using silyl ether-based chemistry, both with without nitroxides. Additionally, these are compared individual made HDPE, LDPE, LLDPE, PP, as well PE blends (comprising LDPE). All were prepared via melt extrusion. Their cross-linking density, storage modulus, tensile properties, reprocessability assessed. For vitrimers, modulus 0.61 MPa was achieved, indicating cross-linked network while also maintaining complete reprocessability. not only provides fundamental insights but presents sustainable pathway for recycling PEs POs into useful materials, hence helping minimize waste.
